The M3 Gran Coupe was already discussed as the replacement of the M3 Sedan sometime last year
in this very forum... I do not see the surprise.
This has obvious
Even before BMW admitting that the GT-Series (of one model) was a failure, the idea of a 3-Series Gran Coupe and even more of a M3 Gran Coupe was obvious. The M3 Sedan could be construed as a sales failure - something like a 3-to-1 ratio sales compared with the Coupe/Convertible- however 2-3000 M3 Sedan sales a year are not bad at all.
Well, just picture an M3 Gran Coupe for $3000-$5000 more than the current M3 sedan and suddenly this is not that much of a surprise. It is just obviously natural.
