I totally agree with you on Mercedes....Their current design is awesome but I think the future is bad, not just for them but generally for the whole car industry...Asia is influenting too much, they are going too fast. I dislike all these Japanese future-cars and crap, that's not way to go, I think that car-design shouldn't go much further, it's cool how it's now.
Audi has a nice future, maybe the best from these 3...we have to see their next model 'sports hope'
and BMW - you never know LOL
