update - my dealer inventory shows one in stock - kinda sketchy as the sticker view only has a vin and color and price, no other details, and no stock number
They start at 55K, but they will come packed around 62K-64K. 451hp/443tq. To some states they will arrive in the beginnings of May. Some dealers are getting them now in states such as FL, TX, CA and NY.
Which bimmer are you trying to compare with the C63?
The M3 and I saw a review on youtube comparing the both of them ... Pure power the C takes it but as a track car the M hands down. The C63 drifts all over the place through the turns .. the M just leaps ahead.
