Well, I do understand those concerns. I left an E92 and went for an F11, but couldn't get used to the gigantic size of the car.
Finding a similar luxury finish in a 3 could have been an interesting opportunity to go back to a more usual size of car for someone driving in the city 50% of time.
But, therefore BMW should consider also pneumatic suspension, comfort seats and a hole different dash-board like the new one of the 7.
Anyway, we'll have to wait to see this new car aside the other 3s into the traffic and testing it before confirming how good or bad it is.
