So I went to the local shop yesterday and asked my sales guy about the M6 (based on some recommendations from you all). Of course they are not out here in the States yet, but I did sit in a few 6 series coupes and crunch the numbers with him. I definately think it is more of an option than before and sort of fits the bill as far as performance sporty above an M3. Still pretty heavy and pricey but I think it could work. I also have an appointment with Jaguar to try out an XK RS-5 that they have here
I'll keep you posted!
