a luxury car, made by Chevrolet, and only affordable to the wealthy
Cadillac is a brand of luxury vehicles, part of General Motors, produced and mostly sold in the United States and Canada. In the United States, the name became a synonym for "high quality", used in such phrases as "the Cadillac of watches," referring to a Rolex or an Omega. This is less prevalent, though still known, in other English-speaking countries (who are more likely to use Rolls-Royce in such phrases).
Cadillac is a station on the Green Line of the Montreal Metro in Montreal, Québec, Canada. It is in the district of Mercier in the borough of Mercier/Hochelaga-Maisonneuve. It was inaugurated on June 6, 1976, as part of the extension of the Green Line to Honoré-Beaugrand.
