I've been to four recent commercial vehicle auctions at a major and well known auction in Manchester, doing my homework before buying a van. Having made notes at each of these, I've noticed that a significant number of vehicles which have clearly been sold at previous auctions are cropping up again the following week. The vans I'm interested in are from a leasing company and when they re-emerge in the following week's auction, they are still being sold in the name of the same leasing company, so it's not a case of them being re-sold at a quick profit, or being unloaded because they have a major fault. What's going on? My best conspiracy theory is that the leasing company have a tame bidder on site to ensure a minimum price for the vehicles and if this is not reached they "buy" the vehicle and re-enter it in the next week's sale. This would clearly require the co-operation of the Auction company. Or is there a simpler explanation I'm just missing? The vehicles are "sold as seen", where the buyer has no real come-back according to the auction regulations, which seems to exclude the explanation that the buyers are simply rejecting the vehicles as unfit in some way. Any suggestions?
