If you want a single vehicle (let's call them 'special vehicles'):

pawn Код:

new SpecVehID_catalinaBuffalo; // For example

public OnGameModeInit()
{
    SpecVehID_catalinaBuffalo = CreateVehicle(...);
    return 1;
}

public OnPlayerStateChange(playerid, newstate, oldstate)
{
    if(newstate == PLAYER_STATE_DRIVER)
    {
        new vehicleid = GetPlayerVehicleID(playerid);

        if(vehicleid == SpecVehID_catalinaBuffalo)
        {
            // They entered catalina's buffalo
        }
}
    return 1;
}

For multiple vehicles you should use an array.
