Listed for sale on Auto Trader by a dealership in Surrey, this particular Bentley Mulsanne was reportedly used exclusively by the British monarch from 2012 to 2014. She's said to have used it during the Diamond Jubilee celebrations that marked her 60th year of reign four years ago, as well as for a visit to Prime Minister David Cameron's office at 10 Downing Street for his inaugural cabinet meeting. We wouldn't be surprised if she took over the wheel from her chauffeur from time to time, either.
The Muslanne is said to have only 5,826 miles on the odometer – 5,000 of which was racked up in Her Majesty's service, secret or otherwise. On that note, there is no mention of 007-esque gadgetry or basic armoring you might expect from a head of state's car. Provenance aside, this being a Mulsanne, it's motivated by Bentley's ancient 6.75-liter V8, not the gauche 6.0-liter W12 or 4.0-liter V8 in the nouveau riche Continental.
It's done up in classic dark green with a tan leather interior and walnut burr veneer trim, and can be yours for £199,850 – or $285k at today's exchange rates. Of course you could pick up a new one for not much more, but then you wouldn't be riding around in the Queen's own wheels, now would you?
