Well, the motorcycle may not happen. That's what I get for getting my hopes up, I guess.
Without getting into the gory details, it looks like the Harley dealer and the Boys and Girls Clubs may not have communicated the terms of the deal clearly. My understanding was that the bid price was the "out the door" price. The dealerships called me and said I'm responsible for all the taxes and everything else. If that's the case, then this is a no-go.
I'm looking at this as a win-win. If there are no hidden charges (over and above the extra 3% already added on), then I get a new Harley. If there ARE extra charges, then I don't get the bike, but that means I'm much closer to getting the Ferrari.
