Z4 ///M roadster??? sounds good

but aside from it being a little more rare for now, i'd say S2K all the way, but only if she drives like a granny or knows how to drive...i'm glad i learned on FWD, because i'm sure i'd have oversteered into a ditch or 4 by now

miatas are cool though, i'd say test drive em all and then make your decision, all the reports in the world won't tell you if you like the feel/sound/driving style of it
