Any big box brand mechanic can fix your car but theyll overcharge you, upsell you on things you dont need and take advantage of the fact that you dont have a vast knowledge of cars.Ive been going to Guy for close to a decade and it has been the best decision that I could have made when it comes to car maintenance. Guy is personable, educational, honest, hard-working, and to top it all off hes reliable. Guy will never overcharge you or try and sell you something that you dont need. Guy is genuinely the best mechanic in the valley, regardless of what kind of car you bring to him. Hes made my Subaru like new while keeping the cost affordable. Guys gone out of his way to help me and thats just not something that youll see at any other shop.Guy is the exact person that you want working on your car!

Guy really knows his stuff! If you have an older Datsun and you need to have work done on it, this is the shop. Guy is very knowledgeable and takes the time to explain whats going on in terms that you can understand. His work is great and his pricing is extremely fair. We need more mechanics like Guy!

My 280z wasnt running and I wasnt exactly sure why. Guy got me in next day and got my Z back up and running perfectly pretty quickly. Hes definitely the most knowledgeable person youll ever meet with regards to anything Datsun related.

Guy was super nice and helpful though the time he was fixing my headlight on my z33 roadster, it was out do to bad wiring and Guy new exactly how to fix it and even taught me a few thing along the way, amazing service and even better stories. 10/10 would recommend . Definitely sending my Z friends here w anything they need and you should too!!!

My daughter’s 350 Z had some mechanical issues. She has used several local mechanics with not much luck. After finding the Z Doctor she will never go anywhere else. He is honest, which unfortunately is hard to find these days, sends updates with pictures and explanations of what he is doing.But the best thing about guy is his knowledge of Nissan vehicles, her Z has never run better.He is a super nice guy and we are so happy we found him.

Professional and knowledgeable, wont take my Z to anyone else, Guys the only one I trust to take care of it properly and is always reasonable on price. I highly recommend the Z doctor to anyone who needs car repairs!

The Z Doctor , Guy, was a valuable and knowledgeable resource in keeping our 1979 Zx safely on the road. Guy did a great job of keeping me informed while the work was underway. Iwill be continuing to do business with the Z Doctor and highly recommend the service to other Z owners.

The man knows and loves Z cars... If you have more faith in someone that feels an emotional connection with the item theyre working with, theres no other place to take your Z 👍

Guy the Z Doctor is genuine has they come. I took my 21 yr old son in to have his 1990 300 Z diagnose. Guy the owner is old school mentality no BS. Just a straight shooter and I appreciate his honesty. Bar down you looking for a mechanic that knows his cars. He is the REAL deal! Very Rare to find a Master mechanic and still very passionate of what he does. Highly Recommend. You will not regret it. JC

Z Doctor is a great resource for ALL things related to Z Cars.

I found my 1972 Datsun 240z in Eagle in 2011 and soon after found about The Z Doctor through word of mouth. After taking my 240z car to Guy he shared things about the Z cars, and my car that I only wished that knew before I purchased mine. The car only had 22,000 original miles but it had also been in a collision that lead me to find another donor car to place this low mileage drivetarin in. Guy performed all the work and has been my only mechanic that I trust will take the absolute best care of it since that time. Guy knows these Z cars inside and out. Guy even has spare parts if needed, or can help locate them. He has helped me over the years from total surgery to adding an after market A/C unit (works great), new stereo and speakers, sound dampening materials in the doors (a must do), along with suspension upgrades, mics fixes, as well as general maintenance. To tell you the truth the list is much more than that but if you need any work done to your Z car dont go anywhere else. Guy knows these cars and cares about his clients. He listens and does great work. I plan on having my 240z for a long time and I know Guy will be the only guy to work on my Z car. Greg Boss, Boise, Idaho

I have a 1973 240Z that Guy has restored in several stages. He is an excellent mechanic and an automotive artist. The interior restoration is impeccable with great attention to detail. The mechanical (brakes, struts, steering, etc.) work is top notch with a effort on Guys part to customize the repairs to the customers desires and at an extremely reasonable cost. The final stages of my restoration will be done this winter and I am looking forward to enjoying my Z into the future. I have owned it since 1974, it is a part of the family so I wouldnt trust anyone working on it other than Guy!

I recently purchased a 1972 240Z. This a bucket list car for me so I was anxious to drive the wheels off it.So I was very disappointed that I couldn’t because it wasn’t running very well. I checked around and it was clear that Guy at Z Doctor was where I needed to go, and I have not been disappointed. He’s been straight with me about all of the issues that he’s seeing and what it will take to get it to be a daily driver. He’s taken my calls every time and promptly answered all of my emails- that in itself is a good enough reason to trust him with your car. He’s old school in that he knows the car inside out, knows how to analyze what’s wrong, and has the skill to fix it. Feel free to reach out to me with any questions you may have. Give Guy a call. I’m very comfortable recommending him.

If you have a Datsun Z car, this IS your guy. He can also help you with Roadsters (1600 & 2000) and probably any other Datsun. He is versatile and easy to deal with. Reasonable price and quality work.

I took our ‘73 Z to Guy for some much needed attention. We have owned it 47 years (3 more payments and it’s all ours😀) but the last 30 years it has been driven very little. Guy tuned it up, corrected some things and gave me a comprehensive list of things the car needs. The engine in this car has never been apart and has 218,000 miles on it.It now runs great and transports me back to that 21 year old kid I once was. It has a few creaks and groans just like me but we grew into them together. When I buckle into the old girl, we can still be pretty sporty.Thanks, Guy. You own the title “The Z Doctor”.I’ll be back.

Stopped by the shop to meet the good doctor and then my car would not start. Best place to have car trouble. The Z-Dr. stopped what he was doing to come outside and get me started. And, no charge for a little help. Thanks a ton. Cannot wait for my scheduled appointment.

My local, reputable BMW (all German cars) mechanic shop was booked out for months, so I brought my 2009 328i to the Z Doctor for a valve cover gasket replacement and water pump/tstat replacement.Used my mechanical insurance with no problem.Car was done in a day on both jobs.Blower motor shut down a week later and brought it in again expecting a full repair again. Turns out the blower motor bearing just needed some lube. Feel like that might have been a full repair at most other shops.Five freakin stars.

Not knowing of any shops specifically working on Z Cars, I Googled some key words and the Z Doctor came up in Garden City ID. Being in Oregon, It was quite a drive away, but since our kids live in Boise, I figured we would check this shop out on one of our visits.Man am I glad I took a leap of faith. Guy Pumpelly, on that first visit to his shop immediately was welcoming and made sure I never felt like an idiot not being a car repair person myself, in fact I know very little about cars inside or out. I definitely have a project car that needs a ton of work. I have the worst mouse issue with every nook and cranny having a full nest with the associated excrement. I asked Guy about doing as much of the non-technical work as I can and he actually encouraged me to do so as my time was much cheaper than paying his professional time. 2 months since that visit, Guy has responded to so many emails from me with questions on how to do this or that on the car. He had very good and right on suggestions to solve the problem at hand. I have not paid Guy anything at this point, although he could charge a consulting fee, but he doesnt, thats not his style. He knows he will eventually have my car in his shop for the majority of the restoration at some point. Guy has a customer service you rarely find anymore. As a business owner myself, Its easy to see that Guy Gets it. Awesome shop and my car isnt even there yet.

I own a 1970 240Z #2696. I had a question about my engine rebuilt that had me stuck. Guy went into detail, over the phone, about how to troubleshoot the problem. He was spot on. When it came time to put the engine in the car, he took me through step by step with each and every hurdle I encountered. I was having an issue with my Pace Setter headers not being flush to the cylinder head. Guy asked if I could get the car from Mountain Home to Boise, and I could. I am very glad I did. So much was wrong and he helped me with all of it. Today we got her to start and run on her own power. I have a few things to wrap up, but for the most part, she is back on the road again! Guy knows his stuff. He is very detailed and will talk you though everything when he explains his workflow. If you have not been to the shop, you must check it out. Give him a call and find out what he can do for you and your Z. Any year, any model!Guy, thank you from the bottom of my heart for the help, support and knowledge you have given me over the past months.

I cannot rate Guy highly enough. He loves his work as well as his customers. Guy strives to not only fix the customers vehicle, but makes certain that everyone is on the same page throughout the process. Guy has a wealth of information, and is always looking for new information and techniques that will help present and future customers. Though he is a Z expert, he works on all cars. My business will certainly go to him from now on.

Took my 240Z (s/n 00676) to Guy and was overwhelmed with his knowledge and ability to recover my engine and suspension which had failed me. Car purrs like new and rides better than new! Very, Very pleased I went to Guy, would recommend him to all my friends that own a Z car of any year. Thank you again.

Amazing service, meticulous work. I trust Guy with all of our vehicles! Super honest and caring folks. Stands their work. Reasonable rates, will work on any make or model. Fantastic, I can relax about my vehicle maintenance!

I have been a Z owner for many years. Last fall I purchased a 1978 280z in Boise to add to my collection in Florida. Guy did a fantastic job doing a complete systems check and needed repairs enabling me to drive the car 2800 miles cross country to get home with confidence. I highly recommend his shop. He is a very knowledgeable and skilled mechanic with a strong desire to do great work and make his customers happy. I am. Thanks Guy!

Such a great atmosphere from the moment you walk in the shop, and always very graciously welcomed by the Z Doctor. He is a very knowledgeable and a very humble guy, it makes it hard not to stay at the shop for hours and talk about various projects he has. I have owned my Z for a little over 4 years and do to the fact I was in high school I wasn’t making a lot of money. The owner made it a mission to do everything he could to help me with anything I needed, whether it was supplying me with quality parts or walking me through step by step how to do things on my car! Needless to say, my Z would not be where it is today if it wasn’t for the Z Doctor. Very thankful for this business!

I have owned my 1971 240Z since 1975. Fortunately, i have not had anything too major to fix on it. I have had my share of mechanics who say they can work on the Z. I decided to finally take some TLC on the car because it is a 71. I went to the Z doctor and now know it is the only place to take a Z. The service went well beyond expectations. Guy knows and loves the Z line. My car runs great. Guy stayed with the project until he was satisfied and I was satisfied with the results.

This man saved my relationship with my car! Over the summer I was having a minor issue with the shifter, and I ended up getting some essential work done which drastically changed the way I thought the car could work.The man knows the intricacies of the Z! Thanks, Doc.

I purchased a 280z for my wife and brought it into the Z Doctor for troubleshooting and advice for service. Guy did a thorough once over and performed some needed service on the car. Unfortunately, service on the gas tank did not go well but Guy took the car back and gladly made things right. I will definitely take the car back!

Amazing work. Far exceeded my expectations and at a fair price. Guy sent me tons of pictures and updates throughout the whole process. It was nice to know you were leaving your car with someone who would care for it like you do.

The BEST and only place to go for your Z car needs. Guy takes pride in his work and it shows every time you get your car back. Ive taken my 300zx twin turbo to him a couple of times now and I have nothing but excellent things to say. I had all my injectors replaced and upgraded as well as a few other things while the car was with him, and it has been running flawlessly ever since. From one car guy to another, thank you Guy!

Went to Dennis Dillon Nissan because my 350z was smoking and was told that I was gonna need a new engine for 8k because , “my o rings were bad” on top of the 917$ service charge. (They took about 1 week and a half to even give me a rough diagnosis). I wasn’t gonna buy a new engine so I took it to the z doctor after a friend recommended him to me and he figured out my problem in 1 day and most importantly saved me 8k. Engine was fine and didn’t need replacement. Fair and honest company.

Amazing work done and very knowledgeable. Very fair price and always available for questions even when he doesnt have your car in the shop. Definitely recommended.

The best customer care I have ever had with a business. Guy makes sure to explain all that you need to know about your car and what it needs. He takes the time to help with questions about how to best take care of your own car. Guy takes pride in going that extra mile for the car and the customer. His work is awesome and his prices are great.Thank you Guy !

Had a clutch put in my 03 350z very very happy with. The professional service the knowledge and the passion that he and his help has for the customer and my car made me feel my car was in great hands.THANK YOU GUY. You have made me a loyal customer.keep up the good work

And now my old friend returns. Bought my 240Z new in 1973 but has not runs for many years. Guy brought it back to life with caring and quality. Now my Z refuses to go to any other MD when needed! Quality service and a very knowledgeable owner. THANKS!

Guy is great specialized mechanic , very reasonable with vast knowledge on Z’s . I personally recommend him for all your repairs . Definitely found my mechanic for my 1996 Nissan 300zx .

I first took my 93 300Z in to Guy (a real doctor of Z cars!) for a once-over after I bought it 14 years ago and havent trusted another mechanic with it since! Hes helped me keep it running strong for 14 years now! I walked into his shop as a 19 year old who didnt know much about cars and he never tried to rip me off or charge me for something that wasnt needed. Because of his honesty, knowledge, openness about pricing/cost, customer service and work ethic I havent gone anywhere else. He treats all of his customers well and isnt happy until his customers are satisfied. Thats hard to find!

Looking for a hard to find part. He had it, pulled it out, cleaned it up and in great condition and was ready in a timely manner for me to pick up!! He is always very friendly and super knowledgeable

Amazing experience!!! I will continue to take my 280z to the Z Doctor for all of my repair needs. You can expect: effective communication, timely repair, reasonable price and quality service.

I took my 1983 ZX to Guy thinking that I had a bad transmission bearing. Half an hour into the shop, he immediately diagnose it to be something else, that something else was the heat shield that somehow it was hitting the driveshaft. His knowledge of the Z is second to none. I asked Guy to go over my car from the front to back and im glad he did because the car needed a lot of work that I did not know I had. While guy had my car he updated me on the worked accomplished via email, with before and after pictures. By the way, from my house to Guys shop is over 150 miles one way. If my car needs future work done, I wouldnt hesitate to take it back to him.

I had bought 1980 280zx with more problems than I could keep track of. I immediately took it over to a shop that I would now not recommend to even the most dire circumstances. This was my first time ever taking my own vehicle in let alone one of its nature. I will leave the name of the shop out for the sake of privacy. Anyways, I took the car to them for more than a handful of reasons and handed over the keys. About four weeks into the process I was feeling pretty uneasy and the shop couldnt find a few of parts. I started looking around when I heard about the infamous Z Doctor. So I picked up the phone and dialed in the number and to my surprise I was met with an EXTREMELY knowledgeable person who told me everything I needed to know. I then got my car back from the commercially owned shop and brought it down and was met with friendly face and great service. Since then I have actually felt involved in the process restoring of my car. If your looking for a mechanic you can trust with your classic car then I would most definitely recommend this place.

The Z Doctor is very knowledgeable, honest & friendly. Hes been our mechanic for over 15 years. We wouldnt trust taking our vehicles to anyone other than this Guy!

Guy is the best mechanic/ maintenance man in the area when it comes to zcars. He is patient and dedicated to doing his work right and in a reasonable amount of time. 10/10 would visit again.

Friendly and very knowledgeable on the z car. Would recommend to anyone needing work done on a z car.

Good work fair price and can trust him very nice for a change

Awesome guy who really cares about Z cars... would recommend him to anyone for auto work for any car at an affordable price

The most honest mechanic Ive ever known. Repaired my jeep and even showed me how much i was being ripped off at my old mechanic. May like his dad even more

Been using Z Doctor for years. Always excellent service, honest answers, and Guy really knows his way around my classic Z!

I have been going to Z Dr. for many years. I am always happy with the results, Affordable and excellent service!!!

One of the most affordable labor rates in the valley and hes a wizard with the Z cars. Ive had four S30 Zs and have taken all of them to Guy.

Always willing to answer questions, and give expert advice
