I recently joined a GTR2 championship and found there is a RUF #4 ?which is not in my stock although I bought the whole package. Also lately found in single player races there are 2 different Corvettes as well not in general stock #29, #24. How and where can I get them as finally not just yellow liveries are available?
There's several more "hidden" liveries in the game, and usually those were used in some competition or created for some other special occasion. They aren't being sold and will only be driven by the AI.
