I got my latest set of new (Michelin Defender) tires today along with alignment on my 2013 Prius. The car noise levels, steering, and ride are much improved. I can't say enough about the personal attention, excellent values and great service at Grand Prix. I highly recommend Grand Prix Tire for your automotive needs. Grand Prix is an honest and competent place of business. Jon D E. Monterey Park, CA 2013 Toyota Prius

Tim and his team TRULY live up to knowing every nut and bolt of BMW's. Tim is Honest, and his prices are a refreshing relief from the dealership! I came to know about Tim when I happened to speak to a young man about his BMW. He highly recommended PHD Bimmer, and I have not regretted it since!! Its a shop for BMW Care that CARES!! Lena

I've had good luck taking my jeep here for servicing. The mechanics here were able to solve a problem that kept causing the engine light to constantly come on. I'd taken my jeep elsewhere in town and the problem was never resolved until I brought my car here. I would definitely recommend this shop. Staff is courteous, professional, and has kept my 15 year old vehicle running smoothly! I will definitely continue to have all work done on my car here at George's Sierra Shell. Nancy

The people at harbor view Mobil were kind, knowledgable and efficient. My car was acting up while I was out of town and both Chris and Tony assured me that everything was going to be ok and kept me in the loop throughout the whole process. The mechanics here are honest, hard working people and I wouldn't hesitate to return whether it be for a big job or routine maintenance. Hannah H. Irvine CA

This service was incredible! The mechanic was timely, knowledgeable, and professional. I had my oil changed and break pads/rotors replaced without leaving my house... and for cheaper than your standard shops. My favorite part? I wasn't being upsold on air filters and fluids! Price and service was transparent. Definitely using Wrench again. Andy W.

Excellent service. Prices are way better than taking it to a dealership and these guys know what they are doing. They even solved a break issue that the dealer couldn't figure out. Den G. Newport Beach, CA

Friendly and quick service.

Got a flat and got it towed here because it was close to Cal Poly. People here are really nice and they fixed my tire for free! Brian was really cool and we had a friendly conversation while Mynor was fixing my tire very quickly. Probably the best experience I had at a car service location. Highly recommend! Jose Jimenez
