Not sure if this is really representative of the 1M "market value." Obviously the seller can ask whatever they want but the true market value will be determined by the price these cars eventually sell for. I would be surprised if any of them sell for the sellers asking price. I bought mine over a year ago for less, with less miles than most listed.
FWIW, I went by the VW dealership selling the VO in Dallas and they are asking $57.5k.
