Warning slight rant

So... the wife an I meet some friends at a Local HD dealer - it was planned that way and then we were all going out to dinner, anyway....
My friend and his wife are looking at a used 2014 Softail slim as my wife and I walk in, nice looking bike- in vivid black. He asks me what I think so I tell him it's a nice looking bike and would be a BIG step up in both physical size and engine displacement from the Sportster his wife now rides. She like the bike, it seems to fit her well. so I ask him what are they asking??? OK sit down here it comes ---- $15,999.00 WTF the thing was only $15,899 MSRP NEW.....And a 2015 is still priced at only $15,899.00... I went as far as pulling out my smartphone and showing him(my buddy) the HD site. Again my friend quietly asked for my opinion so I told him to ask the salesman to justify asking new bike MSRP for a USED bike that had NO mods- not even an exhaust change. Not only that, they wanted to hit them with a "prep" fee of something like $350 -- After a long discussion they couldn't agree on pricing ---- Needless to say the bike is still at that dealer.
I'm just really curious if the used market is so good that dealers are getting new bike prices for used bikes with several thousand miles on them...
