Purchased this car used as a fun car/daily driver on nice days. The performance is incredible. I find that the engine is a little different than older BMW inline-6 in that you have to rev it for power. The exterior has a love it or hate it design but it must be seen in person to render a final opinion. The additional touches that the M car adds to the Z4 (front & rear valence, bigger wheels, quad- exhausts) go a long way to add some aggression to the design. The interior is very comfortable but I have a slim build. Interior design is top notch with the optional carbon leather trim. Bottom line, this is a pure driver's car, those looking for a plush riding luxury car need not apply.
Outstanding drivers car. One of the last pure, raw driving machines left. No fancy transmissions, steering boxes or other lux features.
The nav system is cumbersome and was outdated when new. Avoid it, as an aftermarket system is much more useful.
