My 2002 E53 experience was similar - all new front brake calipers and rotors (and lines) because one of the calipers froze. Had an Indy do this, also the typical DISA, oil filter adapter (just did this on my E70) rear subframe bushings, a couple of front half shafts, and the ultimate - conversion to "normal" PVC as outlines on another forum. Oh, and a new driver's door handle, taking the entire carpet set out due to the sunroof drain tubes leaking - that was fun -, new battery (at least I didn't have to register it), replacement buttons, a new VC gasket.

Other than that, a fantastic ride! Unreal how they corner with the Sport Package.
