Got new roundels for the M3, knock offs from Amazon – I got them to replace the plain black Apex ones, and luckily the ones I got look OEM. The other thing I swapped was the previous owner put on some lame BMW courtesy lights in the door – of which the passenger’s side didn’t even work. Replaced with regular bright LED lights, very bright and perfect fit. To swap these, you pull from the front of the light back out.
