The independent rear suspension from the Mark X was incorporated in the 1963 S-Type, a Mark 2 lengthened to contain the complex rear suspension, and in 1967 the Mark 2 name was dropped when the small saloons became the 240/340 range. The 420 of 1966, also sold as the Daimler Sovereign, put a new front onto the S-type, although both cars continued in parallel until the S-Type was dropped in 1968. The slow-selling Mark X became the 420G in 1966 and was dropped at the end of the decade. Jaguar was saved by its new equally capacious but very much trimmer new XJ6.
