Jerry's Chevrolet

I doubt if this dealer will last more time to come because people will eventually know what you are. I just bought a car there today 04/21/2017 at 12 PM EST and as soon as I left the vehicle started to fail and accelerating/ decelerating itself, when I spoke to the sales rep he told me as soon as you take the vehicle out of the lot is yours no matter what. just 3 hours?? They also told me one price and charged another price that wasn't agreed on. Am trying to see my lawyer and see what I can do now.
