Ok, so we bought something with the intention of using it as part of our challenge car. Since we bought, we've received numerous offers on it as a whole or in pieces. One such offer makes sense for us, and we would like to negotiate a trade.
I'm hesitant because I don't want to run afoul of the accepted behavior or budget rules with the Challenge, and open the door to protests. I'd like to keep everything as transparent as possible to avoid any concerns by judges and/or other teams.
So, what documentation has been accepted? What do you want to see? If at all possible, I'll document as requested and include it with our budget submission.
Thanks for the help!
