Try shoving the rear seat belt clips deeper into their recess? That cause some noise from the rear for me after a passenger sat back there. Besides that, the car has been dead quiet (knock wood).
No _extra_ turbo lag in the 'is' versus the regular 135i. Power is great but the nonlinear throttle mapping sucks. E46 M3 has ~same HP, but WAY better throttle response. I've already considered throttle mapping modifiers...
