A trio of ultra-rare pre-production cars that originally graced the Geneva International Motor Show during the 1950s and ‘60s will take center stage at the prestigious Salon Privé Concours at Blenheim Palace on August 28-29, 2024. Presented by Aviva Private Clients, this exhibition promises to be a highlight for automotive enthusiasts.
A Historic Gathering of Automotive Excellence
Each of these pre-series vehicles – a 1951 Mercedes-Benz 300 S Cabriolet A, a 1960 Maserati 3500 GT Spyder, and a 1961 Jaguar E-Type – represents a pivotal moment in their manufacturers’ histories, making their presence at Blenheim Palace a significant event.
Their appearance is particularly poignant given that the 2024 Geneva International Motor Show will be its last, marking the end of an era for one of the world’s greatest motor shows. This unique gathering not only offers a rare glimpse into automotive history but also serves as a fitting tribute to the legacy of the Geneva Show.
Mercedes-Benz 300 S Cabriolet A: Elegance and Innovation
The Mercedes-Benz 300 S Cabriolet A, first revealed as a prototype at the 1951 Paris Motor Show, epitomizes luxury and innovation. This model, known for its advanced engineering and exquisite craftsmanship, features the same engine and suspension design as the iconic 300 SL ‘Gullwing’.
Hand-built at the Sindelfingen factory, this Cabriolet A boasts a lavish interior with soft leather and a burr walnut dashboard. The Salon Privé exhibit, chassis #188 010 0004/51, is the first factory pre-production 300 S. It made its debut at the 1952 Geneva Show, serving as a showpiece for Mercedes-Benz before its official launch later that year. This car has undergone extensive restoration and remains a testament to Mercedes-Benz’s commitment to quality and elegance.

Maserati 3500 GT Spyder: A Masterpiece of Italian Design
The Maserati 3500 GT Spyder, introduced in 1960, marked a significant shift for Maserati into the realm of series production. Designed by Giovanni Michelotti and built by Vignale, the Spyder featured a shorter wheelbase and a steel body with aluminum components, differing from the all-aluminum Coupé.
Powered by a 3485cc inline ‘six’ engine, the Spyder could reach a top speed of 134mph. The example presented at Blenheim Palace, chassis #AM101.0727, is a pre-production model with unique design features not seen in the final production. Its historical significance and unique attributes make it a standout piece in the Maserati lineage.
Jaguar E-Type: A Legend in Automotive History
The Jaguar E-Type, unveiled at the 1961 Geneva Show, is celebrated for its stunning design and groundbreaking performance. Chassis #885005, one of only three used at the Geneva debut, holds a special place in automotive history as the first E-Type seen in public.
With its unitary body, independent suspension, and powerful 3.8-litre engine, the E-Type was both a technical marvel and a design icon. The example displayed at Salon Privé has undergone meticulous restoration to reflect its original appearance from the 1961 Geneva Show, preserving its legacy as one of the most iconic cars ever produced.
A Celebration of Automotive Heritage
“We are delighted to have such a unique group of pre-production cars that created significant publicity for their respective manufacturers back in the day, now presented in the Salon Privé Concours,” said Andrew Bagley, Concours Chairman. “Each has a unique backstory, showcasing the last-minute engineering and design changes before the production versions hit the market.”
Entries for the 2024 Salon Privé Concours are now closed, but those interested in participating in the 2025 event can contact Concours coordinator Nick Wilkes at +44 (0)7795 213 361 or [email protected].
This year’s Salon Privé promises to be an unforgettable celebration of automotive heritage, offering enthusiasts a rare opportunity to witness some of the most significant pre-series vehicles ever produced.
