context_page_description: The Jaguar 420 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.
context_section_description: Difficulty in differentiating the 420/Sovereign from other Jaguar/Daimler models has meant that they are less well known than other Browns Lane products of the era. Even some Jaguar enthusiasts are unsure exactly where and when the 420/Sovereign fitted into the Jaguar range.
  At the same time as the 420 was released, Jaguar added a chrome side strip and side repeater indicator to the Mark X and a centre bar to its grille. Along with alterations to the interior, these changes were used to justify renaming it the 420G ("G" for Grand). The Motor magazine of October 1966 referred to the 420G as "still one of the best looking large cars in the world today" and commented on the similarity of its new radiator grille to that of the 420. Given the similarity between both the names and frontal styling of the 420 and 420G, the casual observer might be forgiven for mistaking one for the other.
  In 1968 the Daimler DS420 limousine began to be produced, carrying a similarly styled grille to the Sovereign and using the 4.2-litre Jaguar engine in twin carburettor form, and also undergoing final assembly at Jaguar's Browns Lane factory in Coventry, England. Although this car was based on a modified 420G floorpan rather than that of the 420, the existence of a third Jaguar-manufactured model with "420" in its name provides further scope for confusion.
  Similar confusion arises with regard to the Daimler Sovereign. From late 1969 its Series I Jaguar XJ6-based successor continued with the Daimler Sovereign name until 1983, when the "Sovereign" model name was instead applied to the high-specification version of the Jaguar (which by then was into its Series III XJ6 iteration).
