A '96 and '97 actually just sprung to my mind
.
A lot of things are the same:
-An old modified, but always very capable chassis.
-An experianced team running it.
-Up against a "parent" manufacture (Toyota->Dome, and Porsche->Twr)(Manufacture vs. contractor)
-Quick drivers.
But unlike '96 '97, there isn't any real advantages for the Dome over the Toyota and Audi, so the chance of victory is <10%. So it's only a funny thought
