No problems with the transaction. Actually the price I paid was less than the eBay bid I had made- the cars all sell just for their advertised price I guess. I hired a local independent used car inspection that they were completely cooperative with- the inspector worked with them to arrange the visit to inspect and they gave him full access. The inspector was very familiar with them as a dealership and commented on how he has never found any real problems with the vehicles that they sell because they need to have high quality standards to survive selling online like that (it wouldn't take very many bad reviews to ruin their business).
So I was happy. They did all of the DMV registration for me out here in CA too.
Plus John Elway is an investor in them
