on my ps2 i have the mclaren and the carrera gt fully tuned
also have the cars of all top five blacklist people (except for the mclaren from nr.2 and the M3) i hadn't bought anything untill i was third on the list because i was lucky and only missed the pink slip from two cars, i didn't have to spend anything, the carerra gt is teh l33t
btw, the lotus elise is a must get, it hasn't got top speed but it has major acceleration, ideal for drags and races with lot's of curves.
