new GsfCar[2];

GsfCar[0] = CreateVehicle ... // ID 1
Create Vehicle ... // ID 2
Create Vehicle ... // ID 3
Create Vehicle ... // ID 4
GsfCar[1] = CreateVehicle ... // ID 5

// So you got the offset 1-5

OnPlayerEnterVehicle() {
if(vehicleid>=GsfCar[0]&&GsfCar[1]<=vehicleid) {
// This is a GSF Car
// Check if you belong to GSF , if not ClearAnimation
}
}

Or just move onto 2017 and write a dynamic car system where you save the 'GangID' and check if you belong to it.
