GetVehicleModel returns 0 when the vehicle does not exist. You can prevent it in GetVehicleName but shouldn't this function be called at all in the first place for invalid vehicles.

GetVehicleName(vehicleid)
{
    new vstring[18], modelid = GetVehicleModel(vehicleid);
    if (modelid) strcat(vstring, vehicleNames[modelid - 400]);
    return vstring;
