I see some MSM Model 3's on the road, but not nearly as much as white (every single day) or black on the roads when driving around LA. I do see a lot more MSM Model Y's on the road, along with white Y's.
Whenever I have seen another MSM 3, it never looks like my car so I'm happy that I can differentiate myself from others - lowered on 20" Perf wheels w/ spacers for a flush & aggressive look, chrome delete (but that doesn't matter now since there's 2021 Model 3's popping up on the road), CF wing, debadged, euro fog lights (recently installed, not pictured below), along with some other things.
