A crappily made kit on a car which does not have much in the way of performance potential, or more specifically is some kind of regular passenger car which might be modified, is not really my taste. But on plenty of other vehicles, especially sports cars which are in fact shaped like sports cars but are a bit uninteresting when it comes to bumpers and side skirts, tastefully executed kits aren't bad at all. They can even be kind of clunky and still get away with it. For example:

Unacceptable







Acceptable










I think you get the point.

Oh, and your friends suck. You should tell them that the entire internet thinks they've got painfully bad taste when it comes to cars.
