Just a random thought here.....
But the auction is in WI, the same state where the bike was made, and perhaps the bike has always been "close to home" which means something to some "Trekies". (Half of our family worked for Trek (Waterloo & Whitewater) before the company moved nearly everything overseas and several pre '95 models will sometimes throw a curveball at you. This 520 is a very nice bike, but not worth $700 IMHO.)
RE: the mystique; Yes, absolutely.
I agree with you about the Voyageur
