It is a cool looking car, very stylish but you will get bored were soon, kinda boring to drive. People look, but performance and fun factor is no big deal. I have a 2002 911 turbo which is the best sports car in the world, and this new one cannot even compare. Eventhough the $ is close.
I bought my Alpina in Feb, and it's a great car. Unfortunately, some of the parts are rather cheap. I can't tell you how many times I broke the cupholder. And the mirrors rattle and look like they're to fall off while driving down the highway. I recommend this car, but it can be beat. Try a Maserati Cambiocorsa Conv, or a Porsche 911 Turbo before purchasing this Z8.
This is a really superb automobile. It is very fast and has good handling at speeds around 100+ MPH. I am really excited about the Alipina. Although it will no longer be M powered it will still be very fast.
