Great site.
http://car-from-uk.com/motors/cadillac/
This site doesn't have cars from the UK only, but from all over the world, so there is a lot of searching to do.
I brought up 1972 Cadillac Eldorado, and it came up with 10,000 listings.
When I tried to limit the search, it came up as site not listed.

The language of the text is rather strange, as if it was translated by a computer from another language or something.
A new company called the Cadillac Automobile Company was established on 22 August 1902, re-purposing the Henry Ford Company factory at Cass Street and Amsterdam Avenue. It was named after French explorer Antoine Laumet de La Mothe, sieur de Cadillac, who had founded Detroit in 1701.
Cadillac was actually a town in France i think.
