I just got off of a pretty impressive real-time screen sharing demo and Dealer Match also has some pricing inputs from Auction Genius, a sister company of theirs.
My first question to them was how are you different than OVE, since as the person above pointed out, they look pretty similar.
The main differences I can see are the no-contract monthly pricing ($299/mo for now) for unlimited buying, selling, or trading retail-ready units with no per-car fee with a larger selection than OVE. We did several side by side comparisons to see the selection of Dealer Match and OVE for a particular make model year and trim and just in network Dealer Match selection was better than OVE with more transparency then OVE, showing things like inventory aging, etc. Unlike OVE, they offer a pretty solid paid guarantee including even shipping reimbursement for up to 500 miles.
Interesting competitor to the auctions themselves, and as JBurke pointed out, it seems like it is a growing field that will replace a lot of the brick and mortar auction houses for as much as those can be replaced. This tool coupled with Auction Genius would put the sourcing side of the business for us used car guys firing on all cylinders for nationwide sourcing.
