An old slk (not a great car to start with although the new one sounds much better) playing dress-up seems like such a dumb thing to make right now with all the good competition in that segment.
I'd much rather a nissan 350z/fairlady, honda s2000, mazda rx8 (even an mx5), vw golf r32, mini cooper s (works or hartge) and the higher end one crossfires are even getting into boxter, new slk, and z4 territory.
