i am sorry to say this but you are wrong, in the uk we have the ZM Coupe, which is the coupe version of the Z3, it only comes in "m" format, so uprated stuff.

the Exhaust are 2 double ones on either side, but everyone i have seen in Europe and america have only a single or small double on the outside?

has Bmw released a different model apart from in the uk?
Check out Ruzo Gallery and see the White Bmmer!

what was the specs on the us model?
