I have seen a few posts talking about Z8 reaching prices of $180K+ in California.
In the UK, the first Z8's are turning up in the classifieds for 79,995 ukp, approx $116K.
Probably even cheaper in Germany.
Z8 seems to have been universally rejected by euro press. Claim ride is benign (usually only Audi's performance cars get called this!!) and say M5 engine, rear view and interior are only good points.
