Id say the Z4 coupe is like the compact of the E46 its a marmite thing u like it or you don't but its 3.0 so its a winner anyway lol : ) Iam 5.10" rugby players build and find the roadster very comfortable and once u get your seat right the cock pit just moulds to your body perfectly : ) Looking in the wing mirrors at the rear quarters (shoulders) still puts a smile on my face so for me its roadster all the way but do your thing bruv : )
