The Z4 (or all BMW Z cars) will always be niche vehicles. The reason I'm not running out and buying one of the current model, even though I would love a hardtop convertible, has everything to do with the price and weight of the car. I don't want a 3500 + lb 2 seater, and am not willing to pay $60,000 for one either. It really is a shame that the new Z4 is so heavy and expensive, because it is a very good looking car with very impressive performance numbers.
I'm still hoping BMW will remember that there are still enthusiast drivers out here that would really like to see a 300+hp, sub 3000 lb, performance oriented vehicle, with electronic nanny devices that can be tuned down or disabled, with minimal luxury amenities, that can be taken to a track or auto-cross and be fun to drive.
When it absolutely, positively, has to be destroyed overnight! OohRaah!!!
