I really enjoyed this article posted on examiner.com. Its a nicely worded review of the Z4 which briefly hits on all the important points of the car
"Steering is very precise. The only learning curve for me was the massive distance from the front wheels to the steering wheel. Sitting so far back, it’s hard to triangulate exactly where the front wheels are – at first. In time, I was able to precisely position the Z4 on any curve. With a little extra stick (with the traction control off), the rear end slides out on command. On more than one occasion, sliding all fours was not only possible but ridiculously fun. "
