Reviews
Great repair service and staff! I’ve had tons of work done on my Lexus rx350 and they have always gotten me in and out in a jiffy. Really nice guys and reasonable pricing, highly recommend! The previous mechanic I had was a sham and I am very happy to have found this place! My car is basically brand new at this point with 228k miles and runs like new!

As we were leaving the city, our car began making noises from underneath, and we noticed something was hanging down. We stopped at this shops, which was nearby. The gentleman welcomed us, removed a loose plate, and advised us to visit the dealership. He didn’t charge us anything. It’s rare to find such an honest person who doesn’t try to take advantage of you.

Within 15 minutes of dropping my SUV off, they had found the issue with the nosie. A incomplete repair from a different repair shop. They repair the issue. The rates are fair, the technician are professional and they are timely. I understand why this location is recommended by Costco. I recommend them to anyone who needs automotive repair.
