Wow, that dealer lost his A double scribble on that deal Mr. San. Was it in an accident or stolen/recovered? I don't want to sound skeptical, but the Dealer lost ALOT of money on that deal if he sold it to you for that, unless he was reimbursed by a outside source (insurance, trade-in, Promo deal in an accident? etc.)
Anyway, Congrats on the once in a lifetime Opp. I doubt it would ever happen again, unless that dealer wants to go out of business.
AMASS, the price you posted seems to be pretty darn good for a '03 Loaded. Of course, it would depend on the options on the Trailer. Have them through in a new board/bindings or some tower speakers to close it.
