Queen Elizabeth's custom Land Rover with specially designed royal buttons to let her chauffeur know she was ready to drive on is set to sell for £80K

Queen Elizabeth's custom Land Rover, which contains specially designed royal buttons to allow her to communicate with her driver, is set to sell for £80,000.

The late Queen used the green 1978 series III model for public engagements as part of the Royal Review convoy of cars and it contains several bespoke features.

Among unique add-ons is a traffic light system of buttons which enabled the late monarch to alert her driver when she wanted to move on, slow down or stop.

It also has a special plexiglass screen and a handrail so that Her Majesty could stand up while travelling in the rear of the vehicle.

The Land Rover has number plate 3333 LR and was made with rear doors so the Queen could disembark at the back.

It is also adorned with the royal coat of arms, the Queen's personal standard flag waving at the front, and the letters 'GB' engraved above the number plate at the back.

Elizabeth, who died in September 2022, owned the vintage car until 2012, when it was acquired in an auction by British-German businessman Dean Kronsbein for £28,000, the Sun reported.

But the classic car has been listed for sale again after Mr Kronsbein died in a yacht accident.

The fully restored 4x4 is being sold by RM Sotheby's in London, along with the rest of Mr Kronsbein's collection of cars, on November 1.

'This is an extremely unique opportunity', the auctioneer said.

Land Rover has long had a special relationship with the Royal Family, with its cars playing prominent roles at major royal events.

First granted a royal warrant in 1951 by King George VI, the brand was one of a select few to hold four warrants, including those of Queen Elizabeth II, the Duke of Edinburgh, the Prince of Wales and the Queen Mother.
