The thing with most auction sites is that they are not known to the wider audience and with some, it's retailers who end up buying stock for their showroom. There is a local LR dealer who often buys late example with low mileage from some of the better known auction sites, slaps on a hefty margin and puts it on their forecourt and for the most part, sells close to his asking price!

In short, I would take some auction sale prices with a small grain of salt.
