This car appeared on another list that I follow -
I recognised the wording of the advert as the same as the Sammio ad. Then I noticed that it was a very similar price to the Sammio with a similar number of bids (all from "private" bidders). Lo and behold, each of the bids on the cars are at identical times (to within a minute).
The word "shill" springs to mind. There are some twats out there.
And, yes, I have too much time on my hands.
