Buy OEM
Finish is fine but sizing is wrong and these don't fit tight but rattle. About 3/4" movement in all ways, which will lead to scratched paint.
If you've got a beater, these are fine but for my clean M3, I'll buy OEM from FCP or Turner.

My ashtray was broken, so I ordered this one. OK fit, but it broke in three months.
