Princess Diana's Ford escort goes under the hammer in Britain

A car used by Britain's Princess Diana is going under the hammer at auction on Saturday.
The black Ford Escort RS Turbo was driven by Diana from August 23, 1985 to May 1, 1988 and is expected to fetch a six-figure sum.
Diana was previously pictured with the RS Turbo Series 1 outside the boutique shops of Chelsea and the restaurants of Kensington.
The car is being sold by Silverstone Auctions, and is being offered with no reserve price.
Diana preferred to drive her own car and had a member of the Royalty Protection Command (SO14) in the passenger seat.
The car is believed to be unique as the first and only black RS Turbo Series 1, as agreed by S014 and the Ford PR department for reasons of discretion, instead of the only-white manufactured model.
The Ford factory's special vehicle engineering department was tasked to supply the car and it fitted a regular five-slat front grille to assist in the "stealth makeover."
There was also a secondary rear-view mirror for the protection officer with a radio in the glove box, with the cable still visible.
The car has just 24,961 miles on the clock and has been detailed to a nut and bolt concours standard.
It also has a lifetime tracker fitted which can be transferred to the new owner, a spare key, Ford Motor Company internal memos, and period registration documents.
Arwel Richards, a classic car specialist at Silverstone Auctions, said: "The RS Turbo is a driver's car and the late Diana, Princess of Wales was clearly a fan, and it was a fascinating choice for the daughter of an earl, mother of the future king, and the daughter-in-law of the Queen to choose."
