Did Johnny Cash do a Toyota or Mazda commercial between 1997 - 2002?

I only saw it twice, sometime between 1997 and 2002, but it showed Johnny Cash singing the theme song to "Laverne And Shirley" and playing his guitar on a car production line. And I desperately want to see it again. Does anyone know where it might exist? Youtube drew a blank. Google and Vivisimo came up with nothing. I KNOW I saw it, though, it was too unlikely to be a dream or hallucination.
