A friend of mine is considering a Z4 Coupe (sadly not the M). Does anyone have any expriences of ownership? I know a few chaps have had the M version. Any feedback would be much appreciated on service costs, running costs and general day to day liveability (it'll be his daily smoke).
He claims they'll get 32mpg (the 3 litre version) which I struggle to believe

Cheers in advance all!
