A Mini driven by Christine Keele r during the Profumo scandal is on sale for £20,500.
The model owned it in the early 1960s at the height of her liaison with the Tory War Minister.
Its sale comes after BBC series The Trial of Christine Keeler sparked new interest in the affair.
Keeler, regularly photographed driving the silver motor around London, sold it in 1964 after her release from Holloway Prison.
Car enthusiast James Morrison, who knew nothing of its history, bought it in 1989 because he wanted a boot lid for his own Mini.
It then lay unused in a garage and was restored two years ago.
James, 50, used the internet to discover its links with the scandal.

James, of Hitchin, Herts, said: “I only wanted it for the boot lid.
“It sat in my parents’ garage for years. I only considered restoring it after the rise in the classic car market and that’s when I discovered its history. The TV drama makes it a good time to sell.”
In the Profumo spy scandal, which led to the downfall of the Tory government, Keeler was involved with War Minister John Profumo at the same time as a Soviet naval officer. She later went to jail for lying under oath.
It comes as never-seen photos of Christine posing topless as part of a batch sold at auction for £5,800 earlier this month.
They are believed to have been taken in 1966, five years after her fling with Tory minister Profumo.
The scandal was recently dramatised on BBC1, with Sophie Cookson playing Keeler – who died in 2017 aged 75.
The nation has been obsessed with The Trial Of Christine Keeler on TV this Christmas which depicts the true story of how Christine embarrassed the British government after having an affair with a minister when she was 19 years old.
The central crisis arose from perceived national security risks arising due to the 19-year-old Keeler's sexual involvement with British government minister John Profumo , and also Soviet diplomat Captain Yevgeny Ivanov.
Controversial Keeler was then sent to jail two years later for lying to a court about a separate case.
Christine's 49-year-old son is on a mission to persuade Home Secretary Priti Patel to re-examine the case and overturn Christine’s conviction.
