Talk about evoking discussion! haha
Just to verify, ALL wood trim available at BMW is genuine. I agree, there's NOTHING appealing about fake wood trim. It always looks clearly plastic. I think every single japanese car that has 'wood' is fake, including Lexus. It looks horrible. But genuine timbers are an allure if they're applied to the correct trim and colour combinations. I used to own a 1995 Audi 80 and it had the optional burred walnut with a dark velour interior, works very well without being dominant.
The light wood trim I'm talking about is a very light colour, and I think it'll work brilliantly with my black leather interior and bright red exterior. The aluminum trim I have at the moment is fine but to be honest it's not as good as the aluminum my 2006 Volvo S40 had. This one is very scratch prone, and to be honest the big slab of it on the dash sort of looks a bit cheap. The light variegated wood will be quite striking and appropriately aggressive, which is in keeping with the Z4 coupe.
Thanks for the website Smokin, I'll check it out.
