Need your auto serviced you cant go to a better place. John and Jimmy will treat you like family.

Jimmy and John Williams are the best mechanics in the area...very honest and reasonable prices.

We are longtime clients of jimmy & john- best all around! incredibly flexible, always top quality service, and family-owned company. i would exceed 5 stars if possible.

They were rude and didnt even want to talk to me.

Had a great experience today with Jimmy. He was able to service my car same day (I thought I would just be able to get a quote), and he also had extra treats around for my pup. Honest guy that does honest work. We’ve found our new local mechanic.

Best auto repair place Ive ever gone to. Longtime customer who recommends this biz to everyone I know

I Live out of state and needed assistance with a unique job in Austin Texas. I found Nicholas with Cornerstone auto after a half a dozen calls to mobile mechanics. He was friendly, responsive, and eager to assist! He even called me when he was in the hospital to make sure I was informed.Highly recommend to use Cornerstone Auto.LJ Koch

Highly recommend. My wife and I had to make an emergency stop in Tarrytown as we were on a trip from Long Island to the Catskills and several indicator lights lit up the dash of the car. We did a Google search of the area and called several other shops who refused to help as it was 2 pm on a Friday before Memorial Day weekend. The guy at Cornerstone helped me immediately upon my arrival, did a quick diagnostic test, and fixed the problem within 30 minutes. Would definitely recommend this mechanic.

Jimmy does a great job. Professional, very knowledgeable and reasonable. Great to have local services like Cornerstone!

Awesome service extremely knowledgeable

John and Jimmy have a lot of integrity, they have always taken care of me and my family. They dont up-sell, they run a tight ship, and have no time for nonsense.John has a lot of experience with Nissans, and has been helping me maintain my 2009 Maxima.I highly recommend this garage, best to work out a schedule in advance because their time is in high demand.

Excellent local mechanic. Incredibly knowledgable and truly passionate about cars. Will explain the most intricate details about your repair. Will tell you things about your car that even you didnt know. He is beyond accommodating, and the personalized customer service is a factor that is scarce among the competition. You can rest easily knowing that your car is in the best hands at Cornerstone.

Really helped me out of a bind with a hole in my tire. Great guys you can trust.

Jimmy and John are the greatest. I wouldn’t go anywhere else!

No better mechanics around. Honest. Period. Stop wasting your time.

JIMMY AND JOHN ARE THE BEST 👌👍
