The most expensive new car available for purchase in 1965 was the 275 GTB/C Speciale, with a price exceeding $25,000. However, for a more widely recognized production luxury vehicle, the Mercedes-Benz 600 Pullman (W100) was the pinnacle, with a base price of approximately $22,000-$25,000, far surpassing standard luxury sedans of its time.
This distinction matters because the Ferrari was an ultra-rare, competition-focused machine (only 3 units built), while the Mercedes was a bespoke luxury statement for heads of state and dignitaries. In terms of mainstream luxury car pricing, the Mercedes 600 stood alone. The Rolls-Royce Phantom V, another flagship, started around $19,000. The cost of a well-equipped Mercedes 600 could easily double after extensive customizations from the factory’s Special Build department.
The pricing hierarchy of 1965's most exclusive automobiles is best understood through specific data:
| Model (1965) | Approximate Base Price (USD) | Key Context & Production |
|---|---|---|
| Ferrari 275 GTB/C Speciale | $25,000+ | Race-bred, street-legal legend; extreme rarity (3 units). |
| Mercedes-Benz 600 Pullman | $22,000 - $25,000 | The definitive state-of-the-art luxury sedan; ~2,677 total 600 models produced from 1963-1981. |
| Rolls-Royce Phantom V | $18,500 - $19,500 | Traditional British coachbuilt luxury; chassis price before bespoke coachwork. |
| Facel Vega Excellence | ~$13,000 | French luxury coupe/sedan with large American V8 power. |
| Cadillac Series 75 Limousine | ~$10,000 | The apex of American factory-built limousines for official use. |
Market data from period sales records and subsequent auction analysis confirms this pricing structure. The Ferrari 275 GTB/C's price tag was astronomical, aimed at a tiny circle of racing clients. In contrast, the Mercedes 600's value was rooted in its unparalleled technological complexity—featuring a 6.3L V8 engine, fully hydraulic system for windows, seats, and sunroof, and legendary build quality. It was less a car and more a mobile engineering fortress.
When discussing "most expensive," one must consider context. For public purchase of a new luxury vehicle intended for road use with unparalleled comfort and technology, the Mercedes-Benz 600 was the clear and definitive answer in 1965. Its price was not merely for a badge but for groundbreaking engineering that would define the brand's luxury reputation for decades. The Rolls-Royce Phantom V offered traditional craftsmanship, but the 600 represented the cutting edge. The Ferrari, while technically the most expensive, existed in a different, highly specialized realm altogether.

As a classic car specialist, I see valuations daily. For 1965, the factory price sheets are clear, but context is king. The Ferrari 275 GTB/C Speciale was the monetary peak—a racing weapon for the track. But when clients ask about the era's ultimate luxury statement, the Mercedes 600 Pullman is always the file that comes up. It wasn't just a high price; it was a rolling manifesto of engineering ambition. Its complex hydraulic systems, even today, command respect (and hefty repair bills) from specialists, which speaks volumes about its original ambition and cost.

My grandfather was a diplomat in the 60s. The car wasn't just a vehicle; it was a tool of state. When their motorcade upgraded to a Mercedes 600 Pullman, he said the difference was profound. The silence inside was absolute, a moving secure chamber. The sheer presence of it commanded a different kind of attention than a . The Rolls whispered old money; the 600 announced sober, technological authority. He recalled that the cost was considered secondary—it was the only machine that offered that specific combination of imposing size, flawless reliability, and utterly discreet opulence required for the role. That’s what the price truly bought.

Let’s cut through the nostalgia. Looking at pure 1965 dollars, the was the priciest, full stop. But for 99.9% of people, it didn’t exist. The real-world “most expensive” trophy goes to the Mercedes 600. Think about it: $25,000 then is roughly over $200,000 today. For a car! It had power everything—windows, seats, sunroof, even the doors—run by a complex hydraulic system. A regular Cadillac limo was half the price. You weren’t paying for leather and wood; you were funding a rolling R&D lab. It was the S-Class of its day, but on a whole other level, built for chancellors and kings, not doctors and lawyers.

From a collector’s perspective, the “most expensive” title has two layers: original price and ultimate value. In 1965, ’s special competition car topped the price list. However, the Mercedes 600 defined an era’s luxury benchmark. Its value lies in that legacy. Today, auction results show a different story. A pristine 600 Pullman can fetch over $500,000, a testament to its enduring icon status. But a 1965 Ferrari 275 GTB/C Speciale? That’s an eight-figure car, selling for tens of millions. So, which was truly more “expensive”? The Ferrari had the higher ultimate cost ceiling, but the Mercedes 600 carried a price tag that comprehensively redefined what a luxury automobile could and should be for its contemporary buyers. It was the cost of being at the absolute forefront.
