2012 E92 M3 or 2014 435i??

[grarno]

I'm currently in the market for a sports coupe with back seats, and both the E92 M3 and 435i can be bought for around the same money, i.e. just above £30k. I have driven the M3 on track before and love the V8 engine, but performance at least on paper from the more recent 435i is very close and the interior and technology seem to be much better and might make a better everyday proposition. Thoughts?
