I test drove both, a V6 Advance and base 4 cyl, and I don't see why there is so much love for the 4 cylinder model. It felt very underpowered to me. Reminded me of the 320i loaner car I had. The dual clutch transmission was really nice, fired off shifts with the quickness. The rest of the car was nice also, I really liked it overall. But the V6 is probably the one I would get, more than adequate power and the engine felt smoother to me.
With that said, I have to say that this is a really nice car. I can see myself in one and would definitely get one over a 3 series.
