Mine would probably be either a Lancia Delta S4 or an Audi Quattro Sport E2. And here is why. Those 2 cars were the pinnacle of the Group B Rally scene in the mid 80's. Infact the Group B Rally class ended up getting banned because the cars were just getting way to fast to deal with the courses of the day. Both cars symbolize the lengths manufacturers were willing to go to in order to win rallys. But the one thing about the cars is that they are as different as can be in thier respective engineering principles. The Lancia was a mid engine monocoque chassis, while the Audi was a front engined, ladder frame style of constuction, but they both had about the same performance levels. But all in all, I would be happy with either one.
