Victory By Design - if I remember the name correctly - hosted by Alain de Cadenet, who was a racer and drove the featured old cars.
Very factual, lots of history, with some fascinating cars, though largely Euro - but very well presented.

Fun fact: de Cadenet, polished and articulate, and a proper gentleman as the Brits would say, was presenting another program.
Camera on him, he doesn't apparently know that a Spitfire is on the deck and approaching rapidly.
Last second, he instinctively ducks down hard, and spews profanity like a sailor...it's hysterical...
It's on YouTube.
