This is a long review, scroll to the end if you want a tl,dr.
Buyer beware! Cliff's warranty seems to be only a big sales pitch. 2 weeks ago I bought an 09 Chevy Cobalt from him. I was promised a 30 day warranty and he gave a great sales pitch on how he would help with repairs once the warranty was up. Had the vehicle for one day and I started having engine issues. Within a 5 day period, the car was at Cliff's twice and the problem still wasn't resolved. When he was asked as to what repairs he did to the car, he became very unprofessional and downplayed the issues with my car. The fact that the car had acceleration problems, rough idling, and the engine light was on was no big deal to Cliff. He made it quite clear to us that he felt they were minor issues. He clearly does not care about customer service and lacks professionalism. He admitted at this time he didn't know what was wrong with vehicle. It was obvious quick fixes were done. It was agreed I would take the car home to see of these repairs fixed the issue. Within a day, the engine light was on and the car was still not running properly. Called Cliff and left 2 messages, but he didn't return any calls. To make a long story short, I returned the car today and got my money back. If you're considering buying a vehicle from him, be careful.
Tl,Dr: Cliff didn't care about customer service and didn't seem to care about figuring out what was really wrong with my car. His "warranty" doesn't include repairing the vehicle properly. His arrogance and unprofessionalism made this a totally negative experience.
