The owner here is one fantastic human being. I was having a car emergency and the entire time he was a great help. I’m glad he was right down the road because he was a truly kind person. Thank you for all the help and I highly recommend this establishment.

I have been a loyal customer for over 23 years. Jimmy & his brother, Johnny are very knowledgeable and trustworthy. They may not be the cheapest mechanics in town, but they won't rip you off. And I don't think, in over two decades, I have ever been charged for, or pressured to get any service I didn't need.

We lived in Tarrytown for several years and my in-laws are still in town. My father in law has been going to Jimmy for 25+ years and our whole family is convinced that Jimmy is his favorite person in the world. He genuinely gets excited to go get car maintenance at Cornerstone.He's told several of his musician friends about Cornerstone over the years and I know one of the guys still drives up an hour from the Upper West Side to get his car serviced with Jimmy. Hopefully he never retires so my father in law continues to have a reason to live :)Services: Oil change
