My father has a Z4M with brushed aluminum, and it's scratched excessively. He keeps hitting the console area with the seat belt buckle trying to put his seat belt on. The other spot is the ignition key area. He has 2 other BMWs and both of those have the wood trim, and his view is that brushed aluminum is a lot worse to maintain than the wood trim.

He's going to get the panels that were scratched this year for $$$.
