Having owning my 135, and when it was getting serviced my loaner was a 2012 128i, i got in the car and was very soon sadly disappointed. The power was severly limited compared to my 135, but I have a JB4 on it and intakes and it dynoed at 350rwhp and 390 lbs of tq. If I hadn't driven the 135 or owned it beforehand, i probably would have liked the 128i better. Drive both, your decision will be very easy. The N54 power will bring a huge smile to your face!
