Just a curious question after finishing all 4 Nascar challenges. You think that the liveries we won in the challenge are exclusive for us who have completed them? Because I can't imagine any other way they would be obtainable until the time FMEA adds the challenge as part of the Nascar career. But that would be a long way away though. They haven't added any other challenges to career such as "The 500" Aston Martins or the 2015 "Road to Le Mans", latest one added being the F1 challenges.
It would actually be kind of cool having a little exclusive like this to ourselves. A little unfair to those who couldn't complete it while it was available though.
