ETS 2 Mods on PC
The ETS2 Car Mods: This Car vehicle Mods in Euro Truck Simulator 2 is similar to the Bus Mods. You just changed the Dealer/Vehicle type.
You just have to select any Car Mod file and download it, then copy and use that mod in the ETS2 Mods Manager in Game.
I think there might be no Player Level Restriction to use the Car Mods in the ETS2 game.
