Alright i made the system so only the police skins can enter the police cars, But it does not work,
The Enum

pawn Code:

enum TeamCars
{
    Police
}

new Cars[TeamCars];
new Skins[TeamCars];

Checks the skin and car models

pawn Code:

public OnPlayerStateChange(playerid, newstate, oldstate)
{
    if(GetVehicleModel(GetPlayerVehicleID(playerid)) == Cars[Police])
    {
    if(GetPlayerSkin(playerid) == Skins[Police])
    {
    SendClientMessage(playerid, 0x33FF33AA,"You have entered a Police vehicle");
    }
    else
    {
    RemovePlayerFromVehicle(playerid);
    SendClientMessage(playerid, 0xFF0000AA,"Error: you do not have the keys for this vehicle!");
    return 1;
    }
    }
    return 1;
}

PD Skins

pawn Code:

Skins[Police] = AddPlayerClass(280,1544.4233,-1673.0183,13.5584,87.1245,0,0,0,0,0,0);
    Skins[Police] = AddPlayerClass(281,1544.4233,-1673.0183,13.5584,87.1245,0,0,0,0,0,0);
    Skins[Police] = AddPlayerClass(282,1544.4233,-1673.0183,13.5584,87.1245,0,0,0,0,0,0);
    Skins[Police] = AddPlayerClass(283,1544.4233,-1673.0183,13.5584,87.1245,0,0,0,0,0,0);
    Skins[Police] = AddPlayerClass(284,1544.4233,-1673.0183,13.5584,87.1245,0,0,0,0,0,0);
