 In the past 4 years I've had the e60 M5, 2007 M6 cabrio, and 2005 M3 cabrio. This car is built much better than all three of those. M6 and M5 are similar, and some would say in their own class. Yes and no, the M3 seems to be much more agile and nimble, which gives the impression of being just as fast if not faster. Interior is the same as any new BMW car, not that great, but better than the likes of MB or P-cars. Back seat is way better than 911 p-car, but still pathetic. Overall, I think this car actually has some value in it and in today's day and age is affordable for the supercar-like performance and feel. Thumbs up!
