1955 Jaguar XK 140 MC

S 811543roadUnited Kingdom
Engine
3.4L DOHC inline-six with competition cylinder head and dual exhaust
Colour
British Racing Green

A 1955 Jaguar XK 140 MC roadster, dispatched new in August 1955 to a Toronto dealership, finished originally in Cream over Red but subsequently restored to British Racing Green over tan leather. The MC designation brings a competition-derived cylinder head, crankshaft damper, and dual exhaust, lifting 0–60 performance to just over eight seconds. A Borg-Warner five-speed gearbox and brake booster have been fitted for modern usability. A well-presented example of the most capable variant of Jaguar's mid-1950s XK series.

This car's public record is built from its auction and competition history. Register your ownership and privately add your own records to make it a verified Legacy Metrics passport — provenance that backs your car's value at sale and gives your insurer evidence to price against. Roy reviews and verifies every registration personally.

Each chassis record is compiled from public auction archives and links to its source material. Ownership, competition and maintenance entries are extracted from those catalogue listings by an LLM, which can make mistakes — please contact us with any corrections. The summary is Legacy Metrics’ own writing; we do not reproduce catalogue text.

“Full” and “partial” documentation labels indicate how well each entry is corroborated in the underlying sources, not an audit of the car’s physical paperwork. Names of recent or living owners are withheld for privacy.
