Base price seems to be $53k, which is only $12k more than a 335i Coupe.
But it would be only $10k more than a 335xi Coupe, as it comes standard with AWD.
But I think it comes standard with leather, so now only $8k more.
It may come with all sorts of things standard (MMI, NAV perhaps etc.).
Until the US spec and price is released, it cannot be compared. Sure, I expect it to be more expensive than a similarly equipped BMW Coupe, but no more than $4-5k when all is said and done.
This is a lot less than the difference between similarly equipped G37 and 335 Coupes. But when this argument comes around, 1/2 half the forum screams that money isn't everything etc.
