With all the ARN numbers showing at the auction, it won't be hard to track the vehicles when they come up for resale from dealers/ebay etc. Everyone will know what was paid for them, which just might, I repeat might, keep resale prices down a little.
I also note the mileage on many of these at the first auction is very low - I wonder if these are the best of the bunch, so that they set a high sell price which others will feel compelled to follow for lesser vehicles.
