I know of a few cases. At my old job (I worked at a classic car dealer detailing and fixing small things on the cars) a guy put like 20 inch spinning wire wheels rims on a chevelle convertible (the convertibles are very rare) He also put like green shag carpet all over the thing (dash, underside of roof, etc.) He also put those ridiculous purple foglights in the front and back of car. To top it all of, he painted it with flip-flop paint. It changed from bright purple, green, blue, and yellow as the sun hit it. There was a whole bunch of **** that I don't remember. It was pretty ghetto.
