I saw the same episode your speaking of. He was basically hating on the kid for having the audacity to think his car could be labeled as a 'unique' whip so he quoted him that ridiculous price to get out of having to do the job (which in a sense is stupid but it's his business so whatever)
As for the whips they've completed from what I've seen it's been about a 40/60 split from what I like/don't like. I know athletes/celebs are crazy and have money to waste but besides their audio installation and the 1 one in a million upholstery work there's nothing special they do that the avg. person couldn't pick out on their own or find a good shop in their backyard (rims, tints). Other than that I do kinda find it mildly entertaining if I stumble on a marathon but it's not a show I would prog. my tivo for.
