Argg. I've fruitlessly been searching the net for like the last 2 hours and found nothing. I'm going to throw up the answer of Lamborghini Countach just to say something, but I'm 90% sure that's wrong.
EDIT: I still can't get it out of my head that I think it's a Lambo even though I've looked all over. I might be stretching this answer but I'll also guess Lamborghini Diablo.
