And remarkably, there was half an hour's downtime straight after the opening Nissan press conference, because GM had decided to pass up its habitual first-morning opportunity to talk to hacks.
Only Ford, of the Big Three, took a 'business as usual' route, showing improved (and enticing) 2010 versions of the Mustang and of the Mondeo-sized Fusion with impressive new economy credentials.
At least Renault-Nissan chief Carlos Ghosn was able to strike a note of normality in an impressive keynote speech. He adroitly pointed out that wasting time deciding which car company was most in trouble was a fatuous exercise.
Everyone was bleeding, he claimed, and the vast subsidies being sought by car makers in most major countries were necessary to make the radical changes to car design and manufacturing infrastructure that society now demanded. The car was not going away, he insisted. It was more likely that the present world population of 600 million cars would have risen to 2.5 billion by 2050.
To fuel and accommodate them, the world would have to transform itself, Ghosn said, and the changes would need to be paid for. But this was uncharted territory, he explained, through which there was no foolproof route.
Against all this, the debuts of new cars seemed almost beside the point. BMW chiefs had a tough time making the new 7-series sound inviting, but its blood-brother, the new electric Mini, generated much more positive interest, and looked a strong contender for star of the show.
Mini is seeking 500 punters to pay $850 a month to rent a car from its experimental electric fleet, and expects very soon to have to select the lucky applicants from a pool of 25,000 hopefuls. Hacks who've driven the e-Mini speak of heavy steering and wheel fight, but bags of performance and impressive mechanical refinement.
Honda made a much-needed gesture to car enthusiasts by unveiling a beautiful little three-seater hybrid concept called FC concept that looked like a modernised, miniaturised Lamborghini Countach using slightly re-shuffled FCX mechanicals.
It didn't even have an interior, but like many recent Honda efforts it looked deliciously desirable. How come these don't make production?
Then Mazda revealed a pretty but essentially conventional 3 saloon (the four-door, not the five-door hatch that Europe will prefer) which once again carried the typical Mazda body lines and exaggerated front arches introduced quite a few years ago with the RX-8.
It's conventional, especially inside, but slightly bigger than before and thoroughly buyable.
Volkswagen decided, in the light of the times, not to reveal the appealing roadster concept that it has in its back pocket - we should expect it now at Detroit next January - and various other new models were held back as companies fought to horde their dwindling cash reseves.
Lotus's good-looking and lightweight Evora two-plus-two made its US debut and seemed an island of optimism in the gloom. But Bentley's super-power Azure T was almost an embarrassment.
Los Angeles is that kind of fickle place; it was that kind of show.
