The nice lady in the black polo told us all about it. It is fully restored, and Mr. Coppola takes it out on occasion and drives around the vineyard (never on public roads). The Tucker was an engineering marvel. Using an adapted helicopter engine, it got 30 mpg -- unbelievable for a big, heavy 1950's-era car. I will spare you further details.
She further said that the great filmmaker's father immigrated to Detroit and worked in the auto industry. He gave Francis the middle name Ford as a tribute to the manufacturer. When Tucker started a company to manufacture this revolutionary car, the senior Coppola invested.
I really like "Tucker," the movie. When I first saw it, I was astounded by the story of the man who built a better car but was forced out of business by other automakers who had stronger political ties. When push comes to shove, Americans really do not like to compete on a level playing field. We like to win by any means. And who knows better than a filmmaker that the best product does not always succeed in the marketplace?
