Where ever I see a z4m on the road or parked I usually get excited and try to find the owner !! They tend to be petrolhead owned. Hardly ever see them on the road however.
I was tempted when I ordered mine, but when there were two at UK dealers that they could not sell and were discounting at the time, I did not think it would be a wise choice.
I produced it but the info came from somebody else, I can't recall who though
having almost completed my coupe database the numbers are different to the spread sheet so I'm not 100% certain about it, its not a million miles away though
