Ben was great! Would highly recommend him. He was responsive and worked with our busy schedule to come directly to our house. An overall great experience and would definitely use him again.

Great experience taking car in for an issue and getting tires balanced and rotated. Not only did Ben take care of the tires quickly, but he went above and beyond by performing a thorough safety inspection of my vehicle. He made sure my car was completely safe for the road. Ben is honest, professional, and highly skilled—I will definitely be back!

The guy was amazing. He helped me out insanely and got it done in a timely manner and did not charge me much. Drove over an hour and only quoted me $30 for the traveling fee. He did an amazing job and I have not had problems since I am recommending this to everyone.

Ben fixed my AC on my 2011 Kia optima, made a custom exhaust for me on my Cfmoto 675ss. This guy can fix anything and at a good price too.

Ben is very knowledge and fixed my 2022 Suzuki GSXR 750 with no issues! He repaired my clutch pack in a timely manner with honest pricing. Not only did he fix my motorcycle, he fixed my 2017 BMW M2 as well! If you are looking for any mechanical work, Ben can do it all! Will never go back to any other repair facility after working with Ben.
