Back in 2000 I owned a matte silver RX-7. Lived in Newport and Huntington Beach and I don't remember seeing another matte car. The car looked amazing. My friends nicknamed the car The Tuna Trawler.
If I still lived back home I'm sure I'd see a ton of matte cars now. Have yet to see a matte car here in Maryland.
Some cars look good in frozen\matte, others not so much. I really don't think it's a fad that's going to go away, simply because of how the paint\wrap changes the lines of the vehicles it's used on. I think the E92 M3 looks great in the right shade of frozen. Frozen red IS NOT one of those colors.
As always, caring too much about what others think is not a solution for the choices you make about your car.
