Okay here we go.
First of all define the vehicle.

pawn Код:

new faction1;
new faction2;
new faction3;
//ect... how much you need

And then

pawn Код:

faction1 = AddStaticVehicle(model,........);
faction2 = AddStaticVehicle(model,.........);
faction3 = AddStaticVehicle(model,........);
//Ect....

after that
OnPlayerStateChange.

pawn Код:

if(newstate == PLAYER_STATE_DRIVER)
        {
            new vehicleid = GetPlayerVehicleID(playerid);
            if(vehicleid == faction1 && faction[playerid] != FACTIONiD)
            {
                SendClientMessage(playerid, 0xFFFFFFFF, "This vehicle belongs to "Your Faction Name".");
RemovePlayerFromVehicle(playerid);
            }

        }

Add that 3 times on your script.
