Yes, CarMax is sort of the model that we looked at. They are the only player in town that had the scale necessary to apply modern business management principals to their business. But they're margins are paper thin. Too much overhead.
I'm actually very impressed by it. They found a market that is highly fragmented and tried to consolidate. The interesting thing is that they it took them forever to make a profit (and tons of funding). It's great to see, but in my (biased) opinion, they didn't go far enough.
