Bruce--

This is an exact match to my 86 Trek Elance 400--the components are pretty much stock down the line--and it's in better condition from the pics, even though mine is in excellent shape. I own several Treks and this is close to the sweetest ride of all. Could it be there was an error in posting the SN? The serial number pages just list the basic model, which is a 400. My serial number is later in the production run--239257--but it still is listed just like this one as a Trek 400. Who knows where the auction will end but the price is in the ballpark IMHO?
