This could be about the Cadillac De Ville convertible, which is enough of a car to write a few hundred words about. What rose to the top of the froth was that I don’t really know what year this car is from.
That’s the badge on the car. I didn’t see others. Presumably one of our very knowledgeable US visitors knows the serial number and which dealer it was sold from. The part I’d like to deal with is the way GM/Cadillac managed to change the appearance of their cars with such incredible rapidity. These days a car might get a new set of bumpers every three years and even then the difference is often slight due to the need to retain common feature lines and shapes. In the good old days of square, modular styling the car could be chopped up quite markedly and large parts changed without the carried over bits looking wrong.
None of the Wikipedia reference images for the Cadillac De Ville match this. I think it’s a 1970 which is the last year a De Ville convertible could be had.
The styling studios must have been like sweatshops and often decisions on the body style must have been taken very swiftly if they were to make quite big changes to the bodies each year. As I understand it, a drawing was sent to the clay modelling studios where it would be made at full-size and adjusted. Then the 3D form was translated into a die using a device which milled the form into a block of steel. That was then polished by hand and re-polished if the pressed parts did not look right. The huge investment paid for itself because the market was so buoyant. These days the CAD data is used to cut the shape of the dies for pressing the steel or making the injection moulds. Interestingly, the dies are still hand polished.
This car rolled past almost soundlessly. It’s V8 might have been doing 800 rpm for all I know. It suited the car’s lounge-on-wheels style.
