So, another pilot and I are structuring a deal: He wants a new frame (larger hoop), so what we're looking at is he buys the new frame, I buy his old one. We each have engines and harness, so this is just a frame in play. Also they're the same model, just different variations. His is only a few months old, no detectable damage, good condition.
It doesn't seem reasonable to pay full retail for used gear, but this is also a friendly deal; neither is trying to take advantage of the other. So I expect some discount from new price, but since I'm not trying to skin him, I'm undecided what sort of terms to push for. So I'm soliciting the crowd's opinions: What percentage discount would *you* think was fair to both parties?
Thanks in advance!
