No way in hell, not if they did it free. Don't do it, nor Sears or anything like that. They don't give a rats ass about your car. I had a friend that took a 00 S2000 in and they broke his oil pan bolt, stripped it in the oil pan.
Cost him big to get it fixed and Wal-Mart won't pay for it, he filed a complaint and they offered him 5 free oil changes.
Yeah like that would do it for me, all I can say if anyone messes my car up I'm bitch slapping then for sure, just to start, then I'm going off on them.
