Well, you want to demo, probably not gonna happen much these days. The market is too small. MCC hopefully will happen next season, then you can demo, a few anyway.
Buy new. Donek or Winterstick these days for customs, Bruce says he wants' to quit. Euro options exist, but no one's gonna demo in NA. You wanna buy those K's or O's, do it. Racy race style, buy the K, or, those O guys seem like they know they're what doing.
