You are correct, I forgot that for one year it was a heads-up contest; I guess I was so pissed it lasted only one year, I conviently ignored it.
Here is one Corvette attempt, by a single dude against all odds, that showed, nowadays, money comes first, but it was a valiant effort.

Bob,
I was lucky enough to cover most of those races in 2000 for Don's magazine.....and you are right to be disappointed, a battle between Viper and Vette would have been a highlight of any endurance racing championship. However, the Viper had reached the end of its development (and budget), whereas Vette, thanks to Pratt & Miller and Doug Fehan, were only at the beginning of their journey. A case of what might have been.....
The red monster in the photo was another case of a dream that did not realise its potential......
