The last of the 18 Phantom IV cars built was chassis 4CS6 by Hooper for Mohammad Reza Pahlavi, the Shah of Persia.
The Shah had quite a collection of cars, as far as I know he had one of every Rolls Royce model from the 20/25 and so forth. This was his second Phantom IV, his first was a two door drop head coupé by Mulliner, which is one of the two P IV chassis that was broken up. The open version not quite suited for such a large chassis as the doors kept flying open during driving. The body survives on a Phantom III.
This car, 4CS6, was at the Rolls Royce repair shop in Engeland when the Shah was deposed and Iran became an Islamic (IS) Republic under Ayatollah Khomeini in 1979. So you see nothing new about the present IS; the violence remains as ever. The Shah went into exile and died one year later in Egypt.
Next a legal battle started over the ownership of the car and the repair bill. In the end the car went back to Tehran and is now displayed in an automobile museum.
The 1/43 model is by Classic Models which is now in my collection:
