Yeah, the next Z4 is an inch or so longer, and the same for width.
The camoflauge paint scheme really does hide body details, lets hope there's not any more radical "flame surfacing" under there.
It's funny, the Z4 is the only model BMW I haver NEVER been tempted to get. Have had multiple 3 Series, X5s, M3, 7 Series...and almost got a 650i, 535i and X3 3.0si. But never wanted a Z4!
