FactBy 1957 the Series 75 was one of just three Cadillacs still wearing a genuine Fleetwood body — yet the Fleetwood name itself appeared nowhere on the outside of the car.
In 1957 a tubular X-frame without side rails was adopted, giving greater structural rigidity and a lower body without loss of usable space; front-end styling had rubber bumper guard tips and dual circular lamps in the lower bumper, with a dual taillight theme, and the Series 75 was identified by bright metal moldings ahead of the rear wheel openings with seven horizontal wind splits joining a horizontal molding along a conical flare toward both taillamps. It came as a limousine or nine-passenger sedan, both with auxiliary seats, on a 149.7 in wheelbase (236.2 in long in 1957 and 237.1 in in 1958, 80.0 and 79.9 in wide, 63.7 and 61.6 in high, 5,500–5,700 lb) with the 365 cu in (6.0 L) OHV V8 and 4-speed Hydramatic; power was 300 to 325 hp for 1957 (a range, so no single rating is entered). For 1958 there was a new grille with round "cleats", a wider insert with lower bumper guards, dual headlamps, small chrome front-fender fins, less pronounced tailfins and five longer horizontal wind splits. The short-wheelbase Series 70 name returned only for the Eldorado Brougham (1957–58), covered separately.

Owning one
We don’t estimate running costs for a car like this. What it costs depends on its condition, its specialist and how it is driven, and an average would mislead.

Photographs
The 1971-76 Fleetwood Seventy-Five's cabin was so wide it set an interior-width record that no car beat for almost 20 years — not until GM's own full-size cars of the early '90s.
By 1968 the Series 75 limousine packed the biggest-displacement, highest-torque V8 of any American car — serious muscle hidden under acres of formal, chauffeur-driven sheet metal.
By the early 1960s every other Cadillac sedan had gone pillarless — except this stretched nine-passenger Seventy-Five, the one holdout still built with a proper door pillar.
The 1959 Cadillac Series Seventy-Five got a large tailfin and twin bullet taillamps, and its in-house code changed from 7500 to 6700 though the name stayed.
By 1957 the Series 75 was one of just three Cadillacs still wearing a genuine Fleetwood body — yet the Fleetwood name itself appeared nowhere on the outside of the car.
This Fleetwood's seven-passenger formal sedan carried heads of state - a 1955 example served as the Philippine President Ramon Magsaysay's official car.
On the all-new 1950 Series 75, Cadillac made power windows standard but left the Hydramatic automatic transmission as an option — backwards from what you’d expect on an ultra-luxury limousine.
Of this pair, the plainer Fisher-bodied Series 67 was actually the longer car — stretching past its fancier, Fleetwood-bodied Series 75 stablemate.
Every 1938 Cadillac shared the same 346 cubic-inch V8 except the Series 75: it got a higher compression ratio for 5 extra horsepower, which meant its owners had to buy pricier high-octane gas.
This Cadillac had everything going for it — a cheaper, more powerful new V8 and a handsome Fleetwood body — but the Great Depression crushed demand anyway: only 5,248 were sold in 1936.
Rivals
Same body, same money, other badges — tap any card to flip.
This era's Fleetwood limousine rode on a stretched 134.4-inch wheelbase — over eleven feet between the axles alone, on top of everything else making up the car.
A front-wheel-drive limousine was almost unheard of in the mid-1980s — only this Executive and the Cadillac Series 75 offered the format at all.

Checker even pitched a prisoner-transport version of this van, the Convoy, complete with a rear-facing guard seat — nobody ever bought one.
Buick actually undercut Cadillac on price for its 1958 flagship Limited — yet Cadillac still outsold it nearly two to one. Badge snobbery beat the sticker.
The Series 90 Limited's closed cars came dressed in mohair velvet, silk passenger-compartment shades, and wool carpet throughout — despite having no V8 to back up the luxury.
Cadillac executives quietly lobbied to kill this Buick Limited, worried it crept too close to their own turf — even though Buick was building barely 1,500 of them a year.
This stretched DeVille-based limousine came with dual solid-wood writing desks and an in-car VCR with a foldaway LCD TV — luxury so extreme only 781 were ever built.
