6K And Under Auto Sales

Purchased 2009 Chevy Traverse on April 28, 2018. At time of purchase, had verbal promises of repairs to be done that included repairs necessary to turn off the air bag sensor, engine light and tire sensor (among other things) as a contingency of purchase although unfortunately, nothing documented. 3 months later, repairs still have not been completed although taken to them multiple times with promises of "parts ordered" and "car will be fixed". Discussion on July 21, 2018, I was told vehicle was sold "as is" and they were not under any obligation to do repairs. I was also told to not call or come into their office anymore. This caught me very much confused as discussions with Gus (owner), Mike (service manager), and Tony (sale person) were ALWAYS amicable and friendly ... they were only waiting for parts to come in. I would rather they simply stated no work was to be completed months ago instead of stringing me along for 3 months. Actually, I would not have purchased this vehicle in the first place without verbal guarantees as its UNSAFE TO DRIVE without working airbags, car swaying, engine overheating, etc. Taking vehicle to my mechanic on Monday but estimating repairs to be in the $2500-3000 range.
