These were the first series of vehicles that were badge-engineered Jaguars (XJ Series), but given a more luxurious and upmarket finish. For example, the Daimler Double-Six was a Jaguar XJ-12, the Daimler badge and fluted top to its grille and boot handle being the only outward differences from the Jaguar, with more luxurious interior fittings and extra standard equipment marking it out on the inside.
