Good job. Dont let the elephant ears people bother you, your driving a sport sedan not a Ferrari. They look fine. I have never used pre-LCI mirrors, but the vision is so bad in the e90 (couldnt speak to teh e92 since the B-pillar is different) any improvement with bigger mirrors or cameras or whatever is great!
Did pre-LCI mirrors have reverse function (very important to those of us who park parallel and dont have side sensors)?
