Not sure, but I've seen cars that you wouldn't be able to recognize restored, so they could have been rebuilt. I'll never forget Dalmas' flip in the Porsche GT1 at the Petit Le Mans in Road Atlanta the year before; they repaired it, but then again it was a Porsche.
The Petit Le Mans is 1,000 miles or 10 hours, whichever is achieved first; the American Le Mans series, or ALMS (see: [link]), uses essentially the same rules as the 24 Hours of Le Mans and races at several famous North American tracks including Road Atlanta, Road America, Mosport and Lime Rock.

That car looks familiar. It's the CLR Mercedes racer that the Webers and Peter Dumbreck were driving. This one infamously went airborne missing the "Bridgestone" pedestrian overpass just over the fast run to Indianapolis back in '99. Ludwig I think did the late afternoon start, Weber flipped the car during the warm-up, and then turned it over to Peter Dumbreck who was scheduled to run the early evening stint before it took off.
My hypothetical guess. Take it as a grain of salt as you wish.
