That silver one on Collecting cars looks like it’s sat outside uncared for, for a while, there’s algae on the underneath of the rear valance!
The drivers seat especially looks like it’s had a hard life for 33k miles.
Also, those factory mud flaps are PITA. Had them on a silver 3.0Si, they catch on speed bumps. Looked to remove them, but they are screwed on so would require paintwork afterwards. I’m always dubious if a Z4 has one Aero and one standard sill, suggests one has been damaged beyond repair and no replacement available. If that’s the case, what else was damaged?
Personally, I think modifications are ok, as long as the original parts are retained so the car can easily be returned to standard.
