How do you use real cars in Five Reborn?

I’ve seen custom car servers that supposedly have real F150 state trooper trucks etc but nothing shows up for me, just the default in game cars.

Am I missing something? I can’t find any car mods to download, says they’re supposed to be server side.

server side or client side both work but when you join a server with a custom vehicle for ex you will need to download it from the server which can take a few minutes after you spawn the car you want and then youll see it if they show as stock cars then the server probably doesn’t have any
