Finished in elegant Imperial Maroon, a factory color offered by Jaguar during the 1950s, this highly attractive XK140 Drophead Coupé is the beneficiary of a comprehensive, multi-year restoration completed approximately twenty years ago by respected marque specialists XKS Motorsport of San Luis Obispo, California. Executed to a notably high standard, the work emphasized reliability, drivability, and long-distance touring capability while preserving the model's unmistakable character and period charm.

The restoration encompassed a thorough refurbishment of the chassis, suspension, drivetrain, and running gear, with components rebuilt, renewed, or upgraded as required. The legendary XK six-cylinder engine and carburetion system were comprehensively rebuilt and enhanced with a high-capacity aluminum radiator, electric cooling fan, electronic ignition, alternator, high-torque starter, replacement fuel pumps, and a correct-specification wiring harness. Additional improvements include power steering, a new heater core, and a manual starter-carburetor switch, all contributing to improved usability in modern driving conditions.

Further mechanical upgrades include a 3-speed automatic transmission sourced from a Jaguar XK model, replacing the original 2-speed Borg-Warner unit and incorporating a floor-mounted selector. Braking performance benefits from Wilwood front and rear disc brakes, while a stainless-steel exhaust system and chrome 60-spoke wire wheels with knock-off hubs complete the package. New tires, tubes, and a matching spare wheel were fitted, and new wiper blades were installed in April 2026.

The beautifully restored interior features renewed upholstery, carpeting, and rich burled walnut veneers throughout, complemented by a Moto-Lita wood-rim steering wheel. Modern conveniences have been discreetly integrated, including a concealed AM/FM stereo with Bluetooth connectivity and hidden speakers. Exterior enhancements include restored brightwork, J-specification headlamps, auxiliary driving lamps, LED taillamps, fender-mounted mirrors, and a renewed convertible top with matching rear window.

Having traveled fewer than 4,000 miles since completion, this well-sorted XK140 has earned numerous Best in Class and Best of Show awards while remaining ideally suited for spirited touring.
