Alteso says this would put the retail exchange ahead of the wholesale transaction, but we're not sure about that, since the customer isn't allowed to know what the wholesale price is. If the end purchaser doesn't know the wholesale price, then it looks to us like there's still no way to know if you're saving money, or if you're saving more than you would by going to a brick-and-mortar dealership and getting to touch what you're about to buy. But dealers are the remarketing company's clients, so that's where we have to look for benefits, and the upside for dealers would be that they could avoid filling their lots with cars that sit around waiting for customers.
Alteso admits that this is trial-balloon talk right now and there is much to sort out before anything of its kind could happen, even for its target audience. The technology needs sorting, as well as pricing, and certain state regulations could prohibit dealers from selling vehicles they aren't in possession of. Still, if sorted out, the process could get you closer to the day when you can wield a bit of dealer power and attend and bid at wholesale auctions – at least by proxy.
