Derived from a long line of leather-clad full-size Cadillac sedans, the 1990 Cadillac Brougham evolved from the Cadillac Fleetwood Brougham. The Brougham moniker is taken from English statesman Henry Brougham, whose name was given to a covered carriage for two to four people drawn by a single horse. Cadillac used the Brougham name to designate its five- to seven-passenger sedan.

The Cadillac Fleetwood Brougham, like all other full-size GM passenger vehicles, was downsized for the 1977 model year. The new car, as well as the Cadillac Sedan deVille, rode on a shorter wheelbase of 121.5 inches and an overall length of more than a foot. The 1987 model year brought a revised naming scheme for Cadillac’s flagship sedan. The Cadillac Fleetwood Brougham moniker was shortened to Cadillac Brougham.

Our feature The 1990 Cadillac Brougham is powered by a 350 cubic inch V8 backed by a four-speed automatic transmission. Finished in Black and Silver with coach pinstripes and a full padded vinyl roof over a black leather stud interior, the Brougham was equipped with power steering, power brakes, power windows, power locks, power front seats, digital dash, cruise control, wood grain trim, AM-FM/cassette stereo, intermittent wipers, interior guard lights, automatic climate control, door-mounted courtesy lighting, and full wire wheel covers.
