Dude,
No offense, but I think you need to re-read your posts above. I don't see anywhere where you mentioned you were a dealer - or asking on behalf of a third party. Based on everything you posted, it appeared you were the owner wondering what your bike might be worth.
Now, I and a number of other folks here have posted that these bikes have taken a pretty brutal beating over the last year. Yes, the motor is part of the issue, but the 95" SED performed on par or better than most of the other 2004 103's. The big resale hit came after the 2007's were unveiled, so I believe it has more to do with the new 110" / 6spd.
Irregardless, we could debate the reasons why SED's resale market is so poor, but the bottom-line is, that is a fact. If the guy is ill, and can't use it, I would suggest he dump the thing quickly, because it's probably not going to get any better soon. Imho, it's going to take a few years before we hit bottom and the prices level out and start tracking a percentage of the new MSRP's.
I wish your friend luck. Frankly, if he was a friend, and you are a HD dealer, why don't you do him a favor and showroom it for him on consignment? Might as well get some visibility while it's just sitting anyway, right? Who knows, you might stumble on a nice mark strolling by.
My .02 fwiw.
