This was my first time using Cornerstone Precision Auto after my Wheelchair accessible van was sitting for 3 years and the front tire looked almost flat plus I had to purchase a battery prior to contacting them. After scheduling an appointment, the mechanic showed up on time, ran a diagnostic on his machine to pickup anything that was wrong with the van and gave me a quote on how much the parts would be plus the labor to fix the issue on the next visit which would be for his repairment. He give you a choice to buy your part yourself or he can purchase it for you. It would be lower price if you purchase it yourself. He's very professional and stand by his word on his prices and repairs. This is a wonderful company I recommend if you have a car sitting in your yard and don't want to pay a towing fee; let them come to you and eliminate all towing fees.

What a great guy. Ben answered all my questions and went over things in my car that I didn’t know about. He even fixed a small issue on my truck. I feel like I have a personal mechanic now. Will be calling him again soon for other work on car. No worries at all now if I have a mechanical problem. So glad I found him. God bless Ben, he does great work.
