  • I have taken several cars to AR, these guys are the real deal. They are knowledgeable and honest, they know how to repair the cars. They can do everything that a dealership does and its hard to find someone reputable with high end cars like Mercedes-Benz, and Porsche. Always gets the job done thank you guys, thank you Harry.

  • These guys are great! Friendly, honest, and very helpful. I had an issue with my mini a few months back and after being ripped off by the dealer, and a dead end with a different mechanic, I brought my car here. AR Motor Works was able to get me a diagnosis and back on the road in just a few days! This is now the only place I'll bring my car for any type of service.

  • Harry is an honorable repairman man who has literally gone the extra mile for me! He got my Benz in great repair and backed up the parts he sold me. I have enjoyed meeting his whole family. Highly recommended! Goes beyond most repair centers efforts.
