I have a pair of Carbon Fiber overlays off my E92 M3 for sale. They are in very good condition and match the roof's weave pretty well. The tabs were not broken during installation or removal. I ended up just putting the old mirror caps back on the car so I won't be using these. I'm looking to get $200 for them.
I'm located in the SF Bay Area so I can meet up with local buyers too.
