In 1973, the Eldorado series of Cadillac automobiles would surpass the 50,000-production mark, a new record for the nameplate. The Fleetwood Eldorado convertible would serve as the official pace car for the Indianapolis 500 that year and 564 replicas of that machine were built for sale to the public. This is one of those autos, located in Boise, Idaho where it’s been in a storage unit for more than 30 years. It’s available here on Facebook Marketplace for $9,500 OBO.

Cadillac had established the Eldorado as the car to buy if you wanted to stand out from the crowd. They were big, luxurious, powerful – and thirsty (the ’73 editions struggled to get past 12 mpg). Even though the Eldorado had a record sales year in 1973, the new Lincoln Continental Mark IV would outsell it by 20,000 units. This trend would continue through the balance of the ‘70s, even after a major restyle in 1975 for the Eldorado.

For reasons unknown, this ’73 pace car replica was driven into its current lair back in the 1980s and has stayed there since. It has less than 40,000 miles on the odometer, so we wouldn’t think it had developed mechanical problems by that time. The owner (and its only owner) may have thought there would be some huge future upside potential in the car’s resale value.

The body, paint, and interior seem to have held up to the passage of time. Only the convertible top is the only thing that needs replacing once the car gets a thorough wash and wax. However, the running condition of this large automobile is unknown and the seller recommends getting a mechanic involved from the beginning to coax the old car back to life.
