Yeah there are 20 different solid colours and then "apparently" a stealth livery WHEN you gold the X1 Challenge... I emphasize the WHEN because Bronze is EASY! Silver is Difficult but my god I cant even begin to imagine dropping more time to reach Gold!
Not apparently, here is a quick pic I took of mine to show the carbon.
How about that for a "LOOK HOW GOOD I AM!" trophy... Good Work Getting It BTW! 👍 I only just scraped through Silver I dont know how I can get that last little bit! But I will try, try and try again! 
Because I have two in the same livery...If I had them in different liveries I would be holding onto them both... But, thats what happens with random livery prizes I guess...

WOW! what a good looking car.
It's a shame that you can win it so early in the game though, i would have thought that maybe it would have been a prize car for finishing the game. Oh well, just means i can drive it earlier
Yeah, sorry to turn this into a X1 discussion but what colour did you get for Silver trophy? I got a blue that is quite similar to the Red Bull blue colour, in the garage it is quite easy to select the wrong one.
You get a X1 (red bull) for bronzing all three tracks not just one.
Well GT5 has been out officially for 3 weeks and only recently have people been getting the X1 so it's not so early, I am curious as to what we will get for 100%.
I take this back, they're ALL Carbon, the others are just painted, but still Holy **** at the unpainted X1!
Not sure if it is a good idea or if it is just torture... I calculated it is about 14 hrs of grinding on American Champ. > Indy to get 20,000,000 then you need to do that well... 19 times once I take out the 3 I get for the X1 challenge!... 266 hrs of grinding... 11 days, 2 hrs... It is a long term project! 
lol...
