I hope someone can help me out here! I have very vague memories of a rather cheesy 80s movie (it could even be early 90s). I know very little about it except that it featured gangs of punk teenagers driving brightly coloured sports cars. It was vaguely reminiscent of Repo Man, but had a screwball comedy atmosphere. If anyone knows the Troma films, that's the kind of vibe I am talking about- it could even be a Troma movie for all I know.

I know it was shown late at night on British TV about 10 years ago, but don't know anyone who starred in it.

If anyone has any ideas I'd be really grateful.
