With recent fuel, insurance and tax hikes, this car is expensive to run. Not to mention the run flats that this car can go through quickly at £350 a corner. Oh, and the 19" alloys that can split at £400 a corner. Having said all that, its very good looking, fairly good quality, a leap forward over the previous Z4. Incredibly quick, leaving even 3.4litre Porsche's behind on full tilt. Averages 19mpg around town, 40 on the motorway, not too bad for a 300+bhp car. Gets looks wherever it goes. Love the car, but by far the biggest money drain I've ever owned.

Much more refined than the previous model Z4 but doesn't feel as fast as it should as the car has put on a few pounds.
Slight squeaks from the folding hood where it meets the bodywork but otherwise faultless so far.
Very comfortable but needs a rethink over cup-holder positioning...right by your elbows!
Some trims could be of a higher quality or feel for a £40000 car.
Lazy performance through most of the rev range, and quick when needs to be, yet still around 26-28 mpg.
