I deliver auto parts to shops but I can't say i've seen too many things like this. Most of the shops I go to are European shops. People seem to have more money and a little more sense. Although I did come across a blown engine in an 04 Benz. It was a car her husband bought her. Total clueless stuck up bitch. Thought putting STP gas treatment in her oil would help her gas mileage cause "there's oil and gas in the engine."
