Yeah, this was a big thing a few years ago. They had a shrink-wrap vinyl system for applying whole-car ads. It seemed to work well for some people, but I suspect the advertisers decided it wasn't worth the money at that level.
I remember seeing these and wondering if they were in a similar program:
I think they were Isuzu Amigos, and that's Red Bull advertising. I haven't seen one in a couple years.
the aero on that cooper must've been horrible! LOL!
