I don't ever remember seeing even a "cameo" of the car in the background of a commercial.
One was driven by Linda Day George in the "TV Movie", "The Immortal".
I think that was 'Rick' Nelson's as well as the Lime Green 68 Shelby GT500 that Christopher George drove.
But as far as a "Commercial"? Not that I was ever aware of, no.
