I saw an older guy in an AMG SLC43, but the badge was changed to SLC 330. It was definitely an AMG, because it was matte gray with red accents. I don’t think I’ve ever seen anyone make up a fake model number before, with the exception of some people in old BMWs just playing around.
I kind of like the idea. It’s more sleeper-y/less showy like debadging—but without making you look like you’re one of those people who debadged so people wouldn’t know you bought the cheap model—while still suggesting that it isn’t the base model.
