Came in to get a second opinion after one autoshop had told me I needed new catalytic converters. after Dave looked at my car he cleaned my o2 sensors and the car is running great with zero engine lights and zero problems. He also fixed the button on the hatch of my car. I could not be happier that he gave me a good rate and repair. He is an honest mechanic which is hard to come by these days. I will definately be back again.
