#define CLUB 589
#define COMET 480
etc..

new VehicleID[] = {
     CLUB,
     COMET
     etc...
};

new VehicleName[][10] = {
    "Club",
    "Comet"
    etc...
};

--------
new modelid = ModelID[GetPlayerVehicleID(playerid)];

So I know the model ID of the car, and got some nice array with carid's and names...
Now what?! :D
