When Owen Miller was a young man living in Scotland, he didn't even own a car. When he moved to South America 22 years ago to pursue his career as a geologist, that all changed. After a slew of cars came and went, he finally leaned on the advice of his friend and got himself a tried and true Cadillac. But procuring a classic American convertible like the Eldorado took some doing. "There's no Cadillacs here, I imported it," said Miller. When asked why he never tires of the car, which is pushing 50 years old, Miller said, "It brightens other people's days, that's the main thing about it."
