I drove one before ordering a 335 Coupe. It has a lot of older systems in it. The car is plenty fast but I did not get the fun factor I thought I would. I actually found the 335 Coupe a more fun car to drive and it is less expensive. To start with you dont have the 1000 gas guzzler tax and you can get every option available on the 335 Coupe and still be at the same price as the moderatly equiped Z4M.
