A buddy keeps talking about choppers and customs. Seems they drop about in half. He said he's seen $60,000 bikes for around $32,000 in Florida. Seems the guys want the latest and greatest. It's kind of like street rods - the money that goes in is far more than can usually be gotten out, unless the owner can do a lot of the work.
Good luck with it. I'd take a serious look at doing a raffle. Spend six months to a year going about to any festival or whatever, selling tickets. Otherwise take a trip to Sturgis or Daytona, or any other bike meet where customs will be in the majority, with a for sale sign
