The Jaguar 420 (and its Daimler Sovereign equivalent) were introduced in 1966 and produced for only two years, with just over 10,000 made. It was developed from the earlier Jaguar S-Type, retaining its sophisticated independent rear suspension, but fitted with the larger 4.2-litre XK engine and given a modest re-style, with the S-Type curvaceous front squared-off, to better match the rear of the car (which was not altered from the S-Type).
As a sporting Jaguar saloon, the performance of the 420 was highly thought of at the time, with a top speed of more than 125 mph and 0–60 mph in under 10 seconds.
This particular car was first registered in the UK in April 1967. It underwent major renovation in 2009/10 before being imported to Jersey in 2017. Since then, it has racked-up limited mileage but been regularly maintained with any additional work carried out as required.
