production cars with carbon roofs, weren't they the first? BMW often seem to be first to the production line
Quite possibly. They do make exceptionally nice carbon though. It's very very perfect, as you'd expect from bmw. Of course when you buy parts for any of the motorbikes it's still expensive, but it looks expensive and so that kinda helps......a little bit
Don't know for sure, but wouldn't bet against a front splitter in carbon for a BMW from BMW being similar money to a carbon mudguard from DP!
