I had the Z3. This car is a vast improvement. Hugs the road & corners much better. Smoother ride. Many luxury features the Z3 didn't have, such as rear glass window, auto top without anything to hook or unhook, xenon headlights, run-flat tires freeing up trunk space, roomier interior with new retro design, great cup holders! Better stereo sound than the Z3 too.
Favorite features are the great handling & redesigned hard-shell soft top. Unlike the Z3, there's no worry of a vinyl window to get scratched & no need to snap on a cover when the top's down.
No complaints, but I agree with the other rater who wanted it to wash itself. It would be nice to have the iPod connection & Zenon headlights standard.
