When the automobile was completed in July 1950, its delivery was accompanied by a public announcement stating the Phantom IV had been "designed to the special order of Their Royal Highnesses, the Princess Elizabeth and the Duke of Edinburgh". As the car was privately owned when delivered to the couple, it was painted Valentine green (deep green with a slight blue secondary hue) with red belt-line striping. The limousine became an official state car of the United Kingdom upon Princess Elizabeth's accession to the throne in 1952; as such, it was repainted in the sovereign's colour scheme of royal claret and black. This car remains in the Royal Mews and is still used occasionally for royal and state events. For example, it was used at the wedding of Prince William and Catherine Middleton in 2011 to carry Prince Charles and Camilla, Duchess of Cornwall, from Clarence House to Westminster Abbey. In 2018, it brought Meghan Markle to St George's Chapel, Windsor Castle, for her wedding to Prince Harry. In 2022, it transported the new king, Charles III, and the Queen Consort from Buckingham Palace to Westminster Hall and RAF Northolt. The Spanish order On 18 October 1948, Crewe received an order from the Government of Spain for three armoured cars for the use of Generalissimo Francisco Franco: two with limousine bodies and an open all-weather body; this one intended to replace a 1936 Hispano-Suiza J12 with Carrosserie Vanvooren body. While the Phantom IV model was not specified in the order, or even known outside the company at that time, it was decided that the best way to cope with the huge additional weight would be to build the three cars as Phantom IVs, rather than over-burden the Silver Wraith chassis. Especially since the Foreign Office suggested that Crewe could not turn down the order. The passengers were to be immune from a Mauser bullet fired at ten paces, so W. A. Robotham recommended a body from Mulliner’s of Chiswick, which "had many satisfied customers among the more unpopular rulers of the world". A mission to Mulliner’s of Army officers required glass one and three quarters of an inch thick and armour plate. The armour plate was to be almost half an inch thick, and the large floor area required would make the completed weight of the cars over three and a half tons, which would overstress the wheels and gearbox
