The 1959 Cadillac Convertible: Historical Context
Built during the final year of Harley J. Earl's tenure as GM's design chief, the 1959 Cadillac represented the apex of automotive flamboyance. The Series 62 Convertible Coupe—often called the "Fleetwood Convertible"—was the flagship open-top model, priced at approximately $5,200 when new (roughly $52,000 in today's dollars).
Only an estimated 4,409 units of the convertible body style were produced in 1959, making it one of the rarer Cadillac offerings of the era. Its interior was a masterclass in mid-century luxury: power windows, automatic climate control (a first for any production car), a 12-speaker sound system, and a dashboard wrapped in padded vinyl with a chrome-trimmed instrument panel.
What Made the 1959 Interior Special
- Hand-stitched leather bucket seats with elaborate piping and embroidery
- Velour door panels and carpeting with custom-patterned loops
- Chrome-rich dash featuring a "rocket-inspired" gauge cluster
- Powersatin headliner with integrated reading lamps
- Telescoping steering column and power-adjustable front seats
- Rear-seat convenience: fold-down tray tables, cigarette lighters, and ashtrays
The combination of these features made the 1959 Cadillac interior one of the most desirable—and most costly to restore—of any classic car from the late 1950s.
