Definitely going to do this to my C Class but where did you get this wrapping from and what did you use to stick the small chrome piece back onto the cover that opens?
The only real problem was putting the wrapped covers back on the air vents. After 20 minutes of faffing about I decided they wouldn't go on, so as a result I've kept the piano black on the vents. This will then match the screen, side vents and control units.
Here's some pictures of it. It's not perfect, but will do for now.
