On the vehicle you want to link the skin to you must get the id. eg

pawn Код:

new mycar;

mycar = AddStaticVehicle(bla);

after that

pawn Код:

public OnPlayerStateChange(playerid, newstate, oldstate)
{
    if(newstate == PLAYER_STATE_DRIVER)
    {
        new veh = GetPlayerVehicleID(playerid);
        new pskin=GetPlayerSkin(playerid);
        if(pskin != 265 || pskin != 266 && veh == mycar) // Guessing that those are the skins you want in the car
            {
                RemovePlayerFromVehicle(playerid);
                SendClientMessage(playerid, 0x00FF00AA, "This car is only for players with skin 265 or skin 266");
                return 1;
            }
        return 1;
    }
    return 0;
}
