Oh man, I've gotta go with the bread van from Hell (M coupe). As said, it just has so much more character- and 350 Zs are a dime a dozen nowadays. (Not that that is such a bad thing; It speaks for the Z's value per dollar and endearing overall qualities.) I'd like to look at the passing times for these cars, though, as I have driven an M coupe along with several Zs, and the coupe "felt" faster, especially in the mid-range. Then again, maybe it was just me giving in to the sweetness that is the M coupe's inline 6, and the (relatively) abundant torque throughout the rev range. Of course, the Z's motor is also a fine piece, but I think it feels a little truck-like in comparison.

If you could somehow manage to step up to the 315 hp version of the coupe, I wouldn't have to think a second about it.

Then again- if you are really serious about adding a turbo later on, there is probably more out there for the Z.

Still, though, I'm an M coupe guy.
