JAGUAR 420 Rare
As of 2026 Q2, 560 JAGUAR 420s remain registered in the UK — a genuinely rare sight on today's roads. That's down from a peak of 562 in 2025 Q1 — only 100% of the high-water mark, a loss of about 2 cars. Unusually, the numbers are actually rising — up 7 (1.3%) over the past year, as imports and barn-finds rejoin the register faster than cars leave it.

About the 420
The Jaguar 420 (pronounced "four-twenty") and its Daimler Sovereign equivalent were introduced at the October 1966 London Motor Show and produced for two years as the ultimate expression of a series of "compact sporting saloons" offered by Jaguar throughout that decade, all of which shared the same wheelbase. Developed from the Jaguar S-Type, the 420 cost around £200 more than that model and effectively ended buyer interest in it, although the S-Type continued to be sold alongside the 420/Sovereign until both were supplanted by the Jaguar XJ6 late in 1968.
