I love it. M engine and suspension for fun, 5 series type rear seat room with 3 series weight due to stretch in wheelbase, almost the versitility of a small SUV with the hatch, and again almost SUV convenience with fastback sedan looks.
I was going to get an 1M but this thing will have maybe 200 pounds more weight with 100 more hp and actually be able to go places with people and carry things. Looks and sounds great to me.
If you do not like, they will still be making an M3 coupe.
