Princess Diana's car listed at around $82,500 in Jewels in the Crown auction

Princess Diana's iconic 1994 Audi Cabriolet will boast an estimated value of $82,500 (£50,000) when it goes under the hammer next month. The princess bought the green convertible sports car, which she drove to around 4,000 miles, from a dealership in northwest London three years before her death and shared some special memories in the car with sons Prince William and Prince Harry on a number of occasions.

It is among a prized set of 12 classic cars owned by a private gentleman that will be up for grabs on Nov. 12-13 as part of the auction, Jewels in the Crown.

Also included is a Bentley once owned by the Queen, which has been valued at $387,700 (£235,000). The Mulsanne limousine was built in 2012 as a special gift for the monarch's Diamond Jubilee tour of Great Britain. The luxury green motor, which also took the Queen to her only Cabinet Meeting at Downing Street in 2012, was fitted with armour protection, reinforced tires, a walnut burr veneered picnic table and waist rails with inlayed royal crests.

Meanwhile, a 2001 Daimler Supercharged V8, built to the Queen’s specifications, is expected to sell for $99,000 (£60,000). The royal travelled more than 11,000 miles in the car and at her request it features a number of unique modifications, including an adapted armrest with a sliding holder specifically designed to accommodate her handbags.
