Under $100k is a bit too much, there are too many cars that will walk the M3 just under $100k and the M3 is just under $70k fully equipped. The better price would be under $70k. And the only one i can think of is the GTR, stock, if you can get it at that price. The Evo X and a Vette with $5k mods would probably walk it too.

EDIT: I totally forgot about the C63, definitely would walk the M3 on a straightline.
