There were 2 in the race. One fell out for a while for something mechanical (never did find out what) the other was first in class.
GT1 included 2 C-5 vettes, 2 DB9s, 2 Saleen S7s 1 Maserati MC12, Viper, Ferrari 550 Maranello
One of the vettes was second can't remember after that. I do recall that the announcer was impressed by the Ferrari's trial run.
