$46k for a ZHP? No thanks. Besides, if you want a sporty coupe, go for the M3 (SMG is better than the slushbox too if you only want two pedals). You can find plenty of nice, barely used examples for that price. Personally, I would only consider the premium of the ZHP package if you were looking for a sedan, as they obviously don't make the M in a 4-door. I have a 330ci coupe right now, and am thinking trading for the sedan. The coupe doors are big, heavy, and cumbersome. Plus, I don't like the fact that they are "frameless", and have the .5" roll-down on exit/entry. Nice concept, but not worth the trade-off in premature wear on the window components IMO. The (E46) coupes/sedans also share the same performance and are virtually the same weight.
However, a 993 over a 3-series bimmer is the no-brainer!
