I can't even bronze a single one of them. I get so mad. I think I'm a pretty descent at this game, too. I think, even when I win one, I'd probably not drive it much. Just too twitchy and nothing can equal it except other X1s. It's just a novelty.
That all being said, I do want one. That challenge is just too intense for me right now. Kudos on your amazing achievement!
