One of my favorite race cars behind the 787B and a handfull of others. The high end used car place (EXPO I think?) by the Ferrari dealer off 59 in Houston had one of these for a while. They get some incredible vehicles from time to time, they used to have a Maserati MC12 on the show room as well (another one of my favorite "race cars").
I saw this car with Klaus Ludwig race against the McLaren F1 GTR at Laguna Seca. One of my favorites. I still remember the smell of the brake pads and the on/off sound of the engine as the driver got on the gas out of the corners.
