My first car was a piece of crap Plymouth Satellite. Punch the gas while leaving the parking lot at work. There's some water -- so the tires spin really easily.
All of sudden, the exhaust note gets five times louder -- and there's all kind of scraping and grinding noise. Freaking out, I'm thinking I just screwed the engine up really bad. Get out of the car, look underneath -- only to see the rusted out exhaust system had just gotten blown completely off the car.
Threw the parts in the trunk and back seat, went to the auto parts store, bought this crap called "Rock Cast," then drove clear across town, more or less open header -- and bolted everything back together back home.
Bought that car for $1200, sold that car for $1200. And BMW talks about their resale.
