Introduced in October 1954 as a follow-up to the successful and influential Jaguar XK 120, the XK 140 was roomier, more powerful, and otherwise mechanically improved compared to its predecessor—all while maintaining the charm and appeal that made the XK 120 a breakout hit.

This 1956 Jaguar XK 140 MC Roadster (an open two-seater, or OTS in Jaguar nomenclature) bears chassis number S812977. Compared to the Drop Head Coupe, it is undoubtedly the sportier choice; a closed car, or Fixed Head Coupe, was also offered. Completed on 7 November 1956, this car was optioned with the MC specification. This denotes a higher, 210 hp output from its 3.4-liter dual-overhead cam inline-six thanks to a C-Type cylinder head, dual H8 SU carburetors, and a dual exhaust.

This car has been in possession of the consignor since 1990, who recently coordinated its comprehensive restoration. No stranger to this often-challenging task, a similar XK 140 he restored to the same standards previously went on to claim numerous concours and JCNA awards and honors.

The list of well-regarded artisans involved in S812977’s overhaul is long. JP’s European Auto in Huntington Beach, California rebuilt the car’s engine and four-speed manual transmission. The engine and head are original to the car, confirmed by the accompanying JDHT certificate. Additionally during this time, the exhaust headers, which flow into a stainless steel exhaust system, were porcelainized. The original radiator was rebuilt with a high efficiency core and high-flow flex fan. All mechanical gear sits on a freshly powder-coated gloss black frame; a new wiring harness, as well as new fuel and brake lines, run throughout.

The car’s interior, convertible top, and convertible top boot were redone by K&H European Auto Upholstery (note that side curtains are not included with the sale of the car), and cockpit gauges have been restored by Nisonger Instruments. Five new wire knock-off Dunlop wheels, as well as new Vredestein tires and tubes, were obtained for the car. Brightwork was also chrome-plated to a high standard, at this time, and new Lucas side mirrors were sourced.

The finishing touch is the distinctive exterior color—a metallic Ferrari silver, paint code 101C—selected to compliment its owner’s E-Type. The paint was applied by Mark Oja, noted for his role automotive television shows Overhaulin’ and American Hot Rod.

Restored with a concours-quality attention to detail, yet also mechanically prepared for enjoyable touring, this 1956 Jaguar XK 140 MC Roadster is offered with photos and receipts documenting the high-grade work it received.
