The best service of any automotive repair business I have experienced in over 40 years. They were honest, excellent work, and costs for repairs were lower than any other places I had used previously.

I heard a rattling in the rear of my 1993 Jeep Grand Cherokee Laredo. They would not look at it because they said it was too old. It's a classic and I just had the engine replaced and the AC replaced. Including the compressor. It's in mint condition and they still wouldn't work on it.

Dependable and honest. What else do you need in a mechanic? Call ahead for oil changes and inspections to make sure they are doing them that day.

Friendly, honest, quick, and easy on your pocket book. Repaired an electrical issue with headlights/brakes after I installed upgraded LED's that I couldn't get to work properly. Thanks, Gary!

They did it again. I have taken my vehicles to Cornerstone Automotive over the years. They have always provided great value and wonderful customer service. Today they did it again. I took my car in because my car was having multiple warning lights. They promptly saw me, ran a quick test, did a quick visual inspection and determined that it may be an electrical or vehicle computer issue. Unfortunately they couldn't help with the vehicle's computer problem but they went out of their way to eliminate some of the common issues. Thank you again and though I do not look forward to car issues it is nice to know I have a place I can trust.
