Bought A CPO GMC pickup, Was given A 172 item check list of items performed or checked by their certified mechanic. Being a do it your self guy that doesn't take anything for granted the next day I start going over truck my self just to be sure what was said to be performed had been done. Cabin air filter so dirty Had to pry it out with the dirt leaves and bugs. Next crawl under to look at spare tire,find bumper had been replaced and all wires were just left hanging while putting that back in place found bare wires. in all found no less than ten things that on their Certified Pre Owned check list that had been ignored or over looked. I was to pissed to call (afraid of them calling cops on me pissed), so my wife called and they treated her like a moron and then all they had to say that it was noted. What the *** does that mean. Word to the wise buy some where else.
