Sebring 2008: The Audis either broke (one had to replace a turbo), or wrecked (tripping over the Flying Lizard Porsche 911); while the Peugeot broke (hydraulics). Der Fuhrer's cars conspicuously did not break (if memory serves, all the other P2s also suffered some sort of mechanical failure).
Daytona 2003: The DPs were "not ready for prime-time", and all of them broke. (I remember thinking " first race for the being a 24-hour seems a bit optimistic".)
Spa 2003: I had to look this one up, as I didn't see it. That said: From one account of the event, "the NGT winning Freisinger Porsche prevailed after [a] wet[-]dry race and Ortelli’s stroke of genius under the Safety Car (switching off engine on every lap and coasting downhill for 2/3 of every lap)".
Contrast this with IMSA post-buyout, where the ex-GA cars habitually humiliated the ex-ALMS teams, until the rules were rewritten to "make the P2s more competitive", and eventually the DPs were written out of the series altogether. (Umm, I seem to recall that during the War, the contention was that "the ALMS cars and teams are sufficiently superior to the NASCAR-sourced Crapwagons that if both were on the track at the same time, the ALMS teams would win every event". Oops....) So: Yeah, I'm not exactly convinced the PLM that year was on the up-and-up.
I'll be perfectly blunt: I don't trust the current IMSA leadership. And ten years from now, when the fans are asking "why is NASCAR the 800-lb. Gorilla", and "why hasn't sports-car racing taken off" -- the same questions they're asking now, and the same questions they were asking ten, twenty, and more years ago -- well, I'll be sitting here saying "I warned you".
And this does relate to CCES: I see in the various 40-page threads about this rule and that rule the same sort of nonsense which has ruined every sports-car racing series before -- the nonstop rules-lawyering, the constant carping and sniping. I'd very much prefer it not happen here, too.
