Just seeing these cars when in 1976 they were still "cheap" enough to not simply be garage queens - a Mercedes-Benz 300SL roadster, 427 Cobra, Ferrari Daytona Spyder, E-Type Jag...
This is based loosely on a true race, Brock Yate's original Cannon Ball Run - in which, if I am not mistaken, was in 1971 and like the movie, left Manhattan but ended up in Redondo Beach. Yates and Dan Gurney won in a Ferrari Daytona Coupe at 35:54, and surprisingly a Chevy Van was second some 50 minutes later.
Like the actual race there was some contestants who had a specially rigged van with a huge gas tank that was supposed to take them across the country without need for a fill up - nothing said on bathroom breaks.
If you are looking for a movie with some deep social message this isn't the one but if you like cars (and listening to the wonderful noises of the Cobra and Ferrari) this is the movie...
