I used the $9 oil change Groupon here. They came out and told me that "whoever changed my oil last ruined my oil drain plug"....How convenient that I haven't had any problems with it at all. No leaking oil..nothing. turns out - after looking at the bolt, it is obvious that they used one of those air powered drills to try and take the bolt off....therefore the bolt was totally stripped and unusable. It was 6pm and I needed a new oil bolt before I could drive my car. The owner called every parts place in town, they found one at a nearby Napa store. The owner himself went to pick it up and didn't charge extra (but DID charge me for the part!). He still insisted that the "other guy" ruined the oil drain plug. Hmm....not believable. But, atleast he didn't try to charge me labor or anything.... This place is OK.
