04-reg Petrol, Owner for 3 to 5 years

I wanted a sports car and that' s what I got. It has everything I would want from a car manufacturer but I was only able to get these by buying second hand. The cost for all the extras would have been too much for me.
The handling and performance is excellent if a little clinical with DTC and the electronic wizadry that keeps the car safe. Having said that I love the car to bits, I still enjoy driving it ans still feel that twinge of excitement when I get into it. I hope to buy a new model Z4in the next year and hope that the new car gives me as much satisfaction as my present car does

Excellent. It has more than lived up to my expectations. The folding metal roof is wonderful. The double clutch 7 speed gearbox is amazing. The power on the 3.5 idrive is incredible. Enjoy it more to drive than my SLK350 and a Boxter S with PDK that I test drove.

Never let me down mechanically except for the folding roof mechanism. Relative to the power and other similar power and style cars the z4 is a low cost car to maintain.

Good handling, good performance. Too rattly. Steering lacks feel.
Cannot think of another car that meets my requirments so well as my main car for the money.

Fast, sleek, wonderful engine, efficient, minimalist.
But ride quality is poor, and handling could be better.
Utterly reliable.
