Something like that should work:

PHP код:

if ('0' <= Vehicle[0] <= '9')
{
    VehicleID = strval(Vehicle);
    if (!(400 <= VehicleID <= 611)) return SendClientMessage(playerid, -1, "Invalid model ID");
}
else
{
    VehicleID = GetVehicleIDFromName(Vehicle);
    if(VehicleID == -1) return SendClientMessage(playerid, -1, "Invalid vehicle name");
}
