Jack's right - 'tain't cheap. They are aimed at corporate clients, although I did see a race team there when I was at TRC. It was a LONG time ago, and I don't remember who, but I think it was a SCTA team. Someone with a LOT of money, though.
Just to add to the creep-out factor - when I was going there (TRC), they were running a crash sled program, using real, human cadavers! I guess they have to learn this stuff somehow, but YECCCHHHH!! The security guards told stories of 'em sitting around in wheelchairs in a big cooler.
With the Big Three in financial trouble, I wonder if their PGs will be rented out now? Or maybe they already are? When I worked at Milford, NOBODY got in w/o proper credentials, and only GM programs were run. But that was high tides and green grass. Nowadays, not so much.
