Deon DGT classic cars for sale

History of the Deon DGT

The Deon DGT traces its origin to the Mirabeau project, a name referencing the famous curve in the Monaco F1 circuit. Specifically conceived as a reinterpretation of the Ferrari 246 Spyder, the car is not a mere replica but an evocation, focusing on a faithful exterior while implementing practical engineering improvements. Deon produced very few examples—each one typically features unique build touches and craftsmanship, combining British registration as a Deon with authentic chassis and powertrain details.

Model evolution and background

The DGT occupies a niche in British specialist car production, without direct Deon predecessors or successors. Its genesis as an evocation of the Ferrari 246 Spyder set the blueprint; from the start, original units were fitted with a Ford 2.9 V6 from Cologne paired to a Ford LSD transmission. Over time, many Deon DGTs received a significant upgrade with the Alfa Romeo V6 Busso 2.5l 24V—a veritable performance enhancement. Technical innovations, such as a six-speed Lister Bell transmission, are increasingly seen in restored or enhanced examples.

Highlights and special features

A defining trait of the Deon DGT is the high level of customisation and restoration expertise invested in its production. Weight is a focal point: at approximately 950 kg, each DGT is significantly lighter than mainstream sports saloons. The model is known for its bespoke chassis work—often stripped, reinforced, and powder-coated—plus further rigidity from chrome rollover bars. Many cars feature a tailored AVO adjustable coilover suspension and new high-efficiency braking systems. Notable details include 14" Campagnolo wheels, modernised cooling, custom pedal boxes, and hand-upholstered interiors.

Technical Data

Special Editions and Collectible Models

While the Deon DGT was always a hand-built rarity, certain variants have seen particularly notable upgrades. Some extremely rare units are fitted with a custom-made soft-top frame and mohair convertible roof, which is removeable and stowable in the boot. These details, paired with unique paint finishes like Blu Scuro—a classic Ferrari shade—mark these builds as especially desirable among specialist collectors.

Engine, Transmission and Handling

Driving a Deon DGT delivers a markedly agile, responsive experience, thanks to the combination of low mass and balanced chassis geometry. The switch from Ford’s 2.9 Cologne V6 to the Alfa Busso 2.5l 24V powerplant represents a common and rewarding enhancement, yielding roughly 190 hp and strong torque. Most cars are fitted with a custom six-speed gearbox, often from Lister Bell, and receive comprehensive brake upgrades—reinforced discs, pads, and AVO coilover suspension contribute to confidence and control. Renewed A-frames, bushings, ball joints, and uprights raise the dynamic benchmark beyond many standard sports cars. - Ford 2.9 Cologne V6: Recognised as the initial DGT powertrain, reflecting period authenticity.

Interior, Comfort, and Exterior Design

The Deon DGT embodies the forms of the Ferrari 246 Spyder with careful fidelity. Key design elements include reworked and reinforced front spoilers, strengthened side sills, and correctly split engine and luggage lids. Exteriors are frequently finished in hues such as Ferrari Blu Scuro, and equipped with 14” Campagnolo alloys. The interior is reupholstered in leather, including seats, door cards, and boot—complemented by new carpets and custom trim. Dashboards are typically refaced and receive new, period-style instruments. Modern conveniences and specialist accessories—like custom rain gutters, wiper systems, and high-grade seals—round off both cabin comfort and weather suitability.

Other Features

Each Deon DGT is British DVLA registered as a Deon, with matching chassis and engine identification. Advanced details include custom pedal boxes (often Willwood systems), modernised cooling with new radiators and fans, and substantially upgraded wiring throughout. Lighting systems are refurbished to the Ferrari 246 specification—enhanced for both style and reliability.

Summary

With its uniquely detailed construction, performance-oriented engineering, and specialist market position, the Deon DGT stands apart. Built in very small numbers and distinguished by comprehensive upgrades, each example offers a blend of historical homage and bespoke craftsmanship—reflecting its place as the sole focus of the Deon marque.
