Get a nice clean 135i N55. Get a 2012 or 2013... the 2013, 135i"s" came with the PE(Performance Exhaust & PPK added power PLUS pop, pop, POPs!).
What made me choose the 135i over a 128i when new car shopping was when I optioned a 128i the way I wanted too... xenons, heated seats, M-sport... it was only a few grand less than a 135i. That is what made up my mind. The added power is addicting too. Now I have a flash tune and 400 HP doesn't seem like enough!
