Three Rolls-Royce Phantom IV cars from 1952 are used for major ceremonial occasions, such as state visits. Only eighteen examples of the Phantom IV were ever built, all being reserved for royalty or heads of state. Three were ordered by the Spanish government for the use of General Franco and delivered in 1952. They belong to the Spanish Army and are available for use by members of the royal family. One is a 4-door cabriolet version, and the other two are hard-top limousines. A special order was placed for the wedding of the then-Prince of Asturias (now King Felipe VI), when the Phantom IV cabriolet was rebuilt to include armoured protection. Modifications included heavy-duty air conditioning and a special glazed armoured bubble to protect the rear passengers. The modifications cost over €360,000.
