I had not watched if for many years but had good memories of it from seeing it as a youth, and I hired the dvd a few months ago. It was better than I recalled it. One of the best racing movies made I feel, maybe the best and to my eye perhaps the most authentic too.
There is an M or three in the movie from memory, also a Hasselblad appears at one point, possibly even a 1000C. Keep your eyes peeled and you can spot all manner of cameras in the crowds, many of them prosaic no doubt.
The opening sequence with McQueen driving to Le Mans in his 911 has some beautiful cinematography as I recall.
Star of the movie for me (as well as McQueen, of course) would be those incredible 917 flat 12s. I'm not really a Porsche fan, as I tend to prefer the Italian aesthetics to the more functional German road car styling approach (of course there are exceptions) however those 1960s racing Porsches surely rate highly as things of beauty. The 906/908 may be the most curvaceous and feline of them all, but the 917 definitely makes the cut. They possessed style and speed by the bucket load.
Spare a thought for David Piper, too, his big stack in one of the cars (one of the 917s, I think?) in the course of filming the movie, cost him a leg (it's mentioned in the credits as well).
