How much bartering can be done without charging the budget?
For example, let's say some guy down the street is working on a similar project to your challenge project. You hear about his project, and go introduce yourself. After gabbing, you learn that he's got a pile of parts you want, and is willing to trade.
You help him rebuild his motor in trade for his pile of parts. He's thrilled because he's clueless on engines, and doesn't have to pay a machine shop. He gives you the whole pile of parts in thanks for your efforts.
A deal he would have done with anyone, you just happened to be the one to ask. (Not a special relationship).
Part of me says its just more labor you are essentially putting into your Challenger, in trade for parts.
Opinions?
FMV? Free? Other?
