{
SendClientMessage(playerid, RED,"ERROR: You need to be Pilot/Donor to drive Hunter");
RemovePlayerFromVehicle(playerid);
}

if(GetVehicleModel(vehicleid) == 520 && gClass[playerid] != PILOT_CLASS  && gClass[playerid] != DONOR_CLASS)
{

SendClientMessage(playerid, RED,"ERROR: You need to be Pilot/Donor to drive Hydra");
RemovePlayerFromVehicle(playerid);
}
if(GetVehicleModel(vehicleid) == 432 && gClass[playerid] != ENGINEER_CLASS  && gClass[playerid] != DONOR_CLASS)

{
SendClientMessage(playerid, RED,"ERROR: You need to be Engineer/Donor to drive Rhino");
RemovePlayerFromVehicle(playerid);
}

if(GetVehicleModel(vehicleid) == 447 && gClass[playerid] != PILOT_CLASS  && gClass[playerid] != DONOR_CLASS)
