Note: On 10th May 2019, all Citroen cars were removed from the RaceRoom store. Sector3 have not confirmed why this happened, but it is believed that there were license issues. Therefore, all skins for the Citroen cars are now considered "hidden.
Note: All skins for the RUF RT12R GT3 are considered hidden as the car was removed from the RaceRoom store in December 2017, following the first addition of Porsche cars in the game.
