Brought my forester to Pat and Jeremy when I needed a new transmission awhile back. They were able source me a replacement for a reasonable price and quickly. Good guys that know their stuff, have been bringing my Subarus there ever since!

Another *VERY* satisfied customer. Pat and his crew have done a great job keeping my Forester and Mazdaspeed 3 in great shape. They know their stuff and are a pleasure to do business with.

After a long anticipated wait. I had 603 performances instal a iag long block recently. Absolutely the best small performance shop in the area. After using other local shops I hv really enjoyed what they did and how they talked about everything before doing it ther quoat was reasonable better then others in the area by a lot. Recently I went there for oil change they noticed a ball joint loose they didn t even bat an eye took care of it this is top notch business. So I would recommend anyone that ownes a Subaru or other models to take it there. Now I recently needed it tuned they set me up w Matt miner for the tune omg I hv had local shops tune my car in the past but nothing as smooth or power range I was looking to achieve. Matt proved to me today why he has such a great following and loyal clientele. I hv never drove a more responsive Subaru. Hats off to you Matt miner. Just thought I would share my experience with these top notch businesses. These three guys are truly most knowledgeable in there industry then most.

Pat and Jeremy have been my go-to mechanics ever since I discovered 603 Performance 4-5 years ago. I had an issue with my old Subie not starting in very cold weather for like 2 years. Multiple mechanics had me replace different parts and nothing worked. I missed work and a vacation trip because of it. When I found Pat he finally solved my problem, and I ve relied on 603 ever since.I bought a brand new Subaru in 2020 and I ve never been back to the dealer. Pat and Jeremy do all my services; everything is 100% by the book and they do not skimp on parts. Prices are very fair, I get better quality work than my dealership, and I never feel pressured.It can be hard to find a good, trustworthy mechanic. I don t care if my next vehicle is an F150, Pat s my guy.Service: General repairs & maintenance

I consider the team at 603 as a "go to" when I am thinking about what I want to accomplish with a build. They're open and honest about what can be accomplished and have always given me excellent service when I've got work with them. They're responsive and kind - I would recommend them to anyone looking to enhance or maintain their rides!

The guys were very responsive to my needs. I used them to replenish transmission fluid to my CVT, which i accidently drained out. They knew exactly what tools and supplies they needed to do in order to get the job done, because this is a job you cannot do back home. They were much cheaper than dealer. Very friendly, knowledge and professional. I highly recommend these guys.Service: Transmission

I have taken 3 different cars into 603 for repairs and maintenance. Pat is always quick to return our calls and gets us in in a timely manner. Pricing is always fair and he always educates us on the parts that are replaced, and why they were not working properly or safely. I trust Pat and Jeremy with all my auto work. They are honest, hard working mechanics.Services: Electrical repair, Brakes, Battery

These guys are the best in the business no questions asked. I needed a bunch of work done on my WRX, and not only were they extremely responsive in helping diagnose any issues, they always resolve the problems in a timely fashion because they have seen it all. This would be the first place I take any of my vehicles they do great work and are always professional.

Pat was extremely helpful and honest when it came to assessing the health of my old forester. You can immediately tell that these guys know their Subarus, especially the early generation ones like mine and are very passionate about them. A great place to take your car whether it s a project car or a daily driver. They have the foresight to identify what will likely need attention in the future, but aren t looking to jerk you around and say you need a bunch of unnecessary work done. I didn t end up getting any work done this time around due to the condition of my car, but I will certainly take my other Subaru here in the future.Service: General repairs & maintenance

needed to do a walnut blast on short notice and they came through. Even did some diagnosis/troubleshooting for me on an issue and stayed a few minutes past closing so I could make the pickup and drop off of my car. Showed me some before and after pics of the blasting and gave me a few ideas on what could be going on if the issue persisted.Service: General repairs & maintenance

I don t trust bringing my q50 red sport 400 just anywhere, freshly new to the area of New Hampshire and when I tell you, nobody provides service the way they do! Very truth worthy. Best price for service compared to other location s. Highly recommend!!!

I've only ever brought my challenger to the dealer for service, but after this trip I'll stick with 603. Diagnosed the problem extremely fast and had me out the door the day the parts came in. Better service than any dealer I've been to.
