There are vehicle skins for sure, not sure if they're in the pass though. I don't think "realistic" game skins ever really look cool and only the more absurd shit like Overwatch or Fortnite ever have anything worth buying because they're severely less limited. The CoD Nicki Minaj and Seth Rogen skins are kind of funny, but I don't know I'd ever pay money for them personally.
Though, if I got executed from behind by fucking Bob Ross or Grimace from McDonalds or something I'd probably laugh pretty hard and consider it.
