"My bmer if black on black with the premium and sport packages. So far so good. The passenger's side rear weel rim unexplicably broke in two parts. The dealer replaced it along with the run-flat 255 35R19 tire for free. The car is a looker. It runs great. I do find a bit of turbo lag from 0-20mph, but nothing compared with say, the 2003 Auti TT (which I previously owned). Compared to my previous SLK55 AMG, it falls short of power and responsiveness, but overall, I am very very happy with it. The folding hardtop is faster and operates smoother than the SLK's."
"I have owned three porsche 911. I bought the Z4 because of the hard top convertable and the looks. I have had more people comment on the Z4 then any of the Porsche's.
The Z4 has more then adequate power, good handling, comfortable and very good gas milage. Not on par with the 911 but it cost half the price and the hard top convertable is a big plus."
"I own a 2003 BMW Z4 that I purchased new. This car is fantastic and built like a sherman tank. Recently I was sitting at a red light and got hit hard from behind. The guy that hit me took off before I could get any information. Can you believe the only damage to the rear end of the 4 was it lost a few little spots of paint the car didn't bend at all. I definitely will buy another one at some time. I love that car."
"The ultimate roadster. Fun to drive yet incredibly comfortable with plenty of headroom with the top up for those of us 6'2" and taller. Hard top convertible gives you the best of both worlds. As always the BMW approach to cup holders is laughable but if that is an issue then you shouldn't be buying a BMW in the first place."
