OK... So I drove it today
The car is very torque and you can tell it's faster than the 3-series. The brakes and acceleration both feel great! I really like how on the interior BMW did it so that the center console is tilted towards the driver again. The thing I didn't like is the suspension, the car feels really high, on the 3's I feel comfortable throwing it around on a turn, the M3's ask you to throw them around in turns, but I didn't in the 1, it would most definetely need to be dropped.
But I don''t know, I mean that's just how I felt about it. Would I buy one, maybe in a year, but if the 3 series coupe is only a few bucks more in the same range of options then I'd do a 3-series
