As time passed, factories closed, suppliers disappeared, and original components became increasingly scarce.
In 8 Classic Cars With Parts That Are Difficult to Find Today, we explore legendary machines whose rarity makes restoration both rewarding and demanding. From race-bred exotics like the Ferrari 250 GTO to revolutionary designs such as the Tucker 48 and technologically ambitious grand tourers like the Citroën SM, each car tells a story of brilliance paired with complexity.
These classics remain deeply admired, yet maintaining them requires patience, expertise, and often extraordinary dedication from collectors and enthusiasts alike.
1. Ferrari 250 GTO: The Pinnacle of Rarity and Racing Heritage
The Ferrari 250 GTO is widely considered the most valuable car in the world, with only 36 units built between 1962 and 1964. Its extreme rarity, hand-built craftsmanship, and racing pedigree have made it a prized collector’s item, with values exceeding $70 million.
Each car was custom-built, with aluminum body panels shaped using original wooden “bucks” in Italy. Because of this, even minor components are incredibly difficult to find. Mechanical parts often require custom fabrication by specialized craftsmen, and original pieces are closely guarded, available only through exclusive networks of collectors and auction houses.
The 250 GTO evolved from the 250 GT SWB. Modifications were overseen by Giotto Bizzarini to respond to competition from Shelby’s Cobra and Jaguar’s E-type. Aerodynamics were refined through wind tunnel testing at Pisa University, while stylist Sergio Scaglietti lengthened and lowered the nose, extended the tail, and added a full-length belly pan to improve high-speed stability.
The car used a single-cam 3-liter V12 engine derived from the Le Mans-winning Testa Rossa, producing nearly 300 bhp, paired with a five-speed gearbox featuring the signature slotted gate.
Its chassis was lightweight and simple, with a beam rear axle and steel ladder frame. Disc brakes were fitted inside Borrani wire wheels, and suspension consisted of front wishbones and rear leaf springs with a Watt’s link, giving the car agile and predictable handling.
In its time, the GTO was built to race, not for comfort or ease of ownership. Drivers such as Jim Clark, John Surtees, and Phil Hill treated it as a tool to compete. Its soft suspension allowed skilled drivers to manipulate weight transfer through corners, while the low-mounted V12 and compact design improved balance.
On classic circuits like Goodwood, the GTO rewarded precision driving and a confident approach to cornering, offering performance that required both skill and understanding of the car’s dynamics.

The De Tomaso Vallelunga, produced between 1964 and 1967, is a rare and pioneering mid-engined sports car, with only about 50 to 58 units ever built, including a handful of aluminum prototypes.
Alejandro de Tomaso’s first foray into road cars, the Vallelunga, combined bespoke engineering with parts borrowed from other manufacturers such as the Triumph Herald, Volkswagen, and Ford. Its rarity, prototype-like design, and hand-fitted components make restoration exceptionally difficult.
Even components from one car may not fit another, and original parts such as the cast-magnesium Campagnolo wheels, fiberglass body panels, Perspex rear window, and unique trim are virtually impossible to source today.
The Vallelunga’s engineering was revolutionary for its era. It employed a pressed-steel backbone chassis, using the 1.5-liter Ford Kent engine and VW/Hewland gearbox as semi-stressed members, a technique derived from Formula 3 racing. This arrangement improved weight distribution and lowered the center of gravity, creating a driving experience that emphasized balance and responsiveness over raw power.
The chassis and suspension design were unique, including magnesium alloy wheels specifically cast for the car and a pressed-steel backbone that supported the engine structurally. Specialized components, such as Campagnolo disc brakes, required custom fabrication, while bodywork was hand-formed and fitted individually, meaning no two cars were identical.
Despite its modest 104-horsepower engine, the Vallelunga is celebrated for its exceptional handling and driver engagement. Weighing just 726 kilograms (1,600 pounds), the car responds precisely to inputs, with steering often described as “telepathic.” Its low mass over the front wheels allows neutral cornering and a tactile connection to the road, creating what enthusiasts call a true “momentum car.”
The engine is reliable and easy to tune, allowing drivers to exploit the chassis limits without excessive risk, though NVH (noise, vibration, and harshness) can make long-distance touring fatiguing due to the engine’s integration into the backbone chassis.
Stylistically, the Vallelunga is a 1960s Italian design triumph, with fiberglass bodywork by Ghia, a glass fastback showcasing the engine bay, and a cockpit-like interior featuring classic Veglia gauges and a wood-rimmed steering wheel. Its low stance, clean curves, and attention to detail give it a prototype aesthetic that precedes De Tomaso’s later successes with the Mangusta and Pantera.
Today, the Vallelunga is a highly coveted classic for connoisseurs who value finesse, historical significance, and driving purity. With such a small number surviving and most parts long obsolete, it remains one of the most delicate, hand-crafted mid-engine cars from its era, representing a perfect balance of innovation, rarity, and tactile driving pleasure.
