Why it matters
The 420G was the final development of the big Jaguar saloon line that began with the Mark X of 1961. The Mark X was Jaguar's largest car, and the largest car in Britain with a unitary body at the time of its launch.

| What is counted | Figure | Basis | Status |

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.
History
Jaguar introduced the Mark X at the 1961 London Motor Show to replace the eleven-year-old Mark IX. It had unitary construction and independent rear suspension similar to the E-type, and used the 3.8-litre XK engine with three carburettors; Jaguar quoted a top speed of 120 mph. A 4.2-litre version in 1964 improved the power steering, brakes and transmission, and the 420G followed in 1966. After the XJ6 arrived in 1968 production ran down in 1970, with just over 24,000 Mark X and 420G cars made in total.
