That is an exceptional, classic set-up! You MUST have seen The Last of the Ski Bums, one of the first ski films with a 'plot'.
The three bums travel around in an almost identical car to yours, a gold '66 912 (I believe), with a luggage rack on top, and two ski racks on the back.
There is also some very good racing footage, and Killy wins the Kandahar DH race that the 'bums' are spectators at.
It comes as part of the Classic Ski Films box set. Also included is the 1971 The Performers by K2, but that is another story.
