The car shown here is a genuine Brougham sedan, which was the top-of-the-line Omega in 1984. It boasts plush crypto-velour upholstery, a factory AM/FM/cassette deck (with fast-forward and rewind, for the real high-rollers), and a list price of $8,104. That's just under 19 grand in inflation-adjusted 2016 bucks.
Still, the Omega/Citation/Skylark/Phoenix wasn't a bad-driving car, when it ran... unless it came with the cheapskate base engine, the primitive 2.5-liter Iron Duke pushrod four-cylinder. Owners of stately full-sized Oldsmobile Broughams of years past took one listen to the tin-can-full-of-rocks ambience provided by the Duke and ran at top speed out of their Olds showroom, never to return. No great Oldsmobile songs were ever composed about this car.
No doubt about it, this was a "smooth-ridin' road-huggin' high-fashion eye-catchin' quick-stepppin' fuel-sippin' pump-passin' pocket-pleasin' front-wheel-drive Omega from Oldsmobile!"
It's unlikely that R. L. Dukes in Chicago sold this car when it was new, since there's not a speck of Illinois rust on it. Perhaps Cal Worthington and/or his dog, Spot, were part of the deal.
