"I had my 2006 Jeep Grand Cherokee WK in with this shop to have the pinion gears and pinion seal replaced. I was extremely pleased with the service provided. Every bit of work was gone over in detail, and the staff was friendly and helpful. I'll definitely recommend this place and the people here to anyone, and I'll bring my vehicle in again without hesitation if needed. UPDATE: 08/11/2020 - Had my Jeep in again for brake work due to the passenger front caliper hanging up. The mechanics there are, once, again, recommended. Also, a slight issue with previous work that I was told about and that was fixed at no charge. UPDATE: 09/09/2020 - Had my Jeep in again due to a previously known major exhaust leak from the manifolds. The gaskets for both left and right banks were replaced with new hardware as well. Excellent service as always!" -- David C.

TestimonialsOur happy customers

I'm 37 and have been taking my cars here since I started driving. My dad does too. They've always been up-front and honest about costs and repairs. If there is a repair that isn't necessary or can wait awhile, they tell me that too. I have nothing but good things to say about this business and I highly recommend them.
5 star review by Michael G.
Had a good feeling about this place after reading reviews all over the web. After meeting the owner Jim I knew we were in good hands. I am so grateful for the job they did and their reasonable prices. My daughters 2002 Malibu is running like new. We found a neighborhood mechanic we can count on, Thank you!
