I would also prefer the LWB version of the B7! Just because I like the design of it and my friends would have more space in the back. But normally, I drive alone or with only one person at the passenger seat.
At the moment I don't know, which type of colour I would choose. Alpina blue doesn't really harmonise to the noble but specific character of the car. Mine would be black or silver with dark interior. Or I would choose an Alpina B6, but the B7 is also very specific!
