I played the first one and it was very good, but can't bring myself to spend $50-ish on the new one... when it hits about $25, I will probably pick it up.
Interesting addition, and nice car... I kind of want a Z4 coupe, but would probably go for the 3.0si for practical reasons. Then again, I will probably never get one because it isn't really practical at all, but it would be great on the auto-x course.
Some unsuspecting person will be quite envious thinking that your 'company' actually provided you a Z4m as a company car
p.s. I spent 6 weeks in Singapore in summer 2006... awesome food there if you like variety and all kinds of Asian food! (I loved it anyway). But for owning a car there, not so great...
