According to Wikipedia, a Grand Tourer can be defined as: “a performance and luxury automobile capable of high speed or spirited long-distance driving. The most common format is a two-door coupé with either a two-seat or a 2+2 arrangement”.

The term derives from the Italian ‘gran turismo’, and is a tribute to the tradition of the grand tour, which sees GTs of various marques and models embarking on long-distance, high-speed journeys in both style and comfort.

According to author Sam Dawson, “the ideal is a car with the ability to cross a continent at speed and in comfort, yet provide driving thrills when demanded”, and it should exhibit the following:

• The GT should have been devised by its designers specifically as a Grand Tourer
• It should be able to transport at least two in comfort with their luggage and have room to spare

In line with recent news that classic cars are becoming an increasingly good investment opportunity, we’ve compiled a table, using data from Classic Car Buyer, illustrating more clearly the rising values of all XJS models, no matter what the condition.

The Classic Car Buyer price guide is compiled with reference to a variety of sources, including clubs, auction results and advertisements, both printed and online. It is impossible to accurately value a specific vehicle without examining the car first.

The listings below are intended to provide a useful guide only, and were valid on 22nd July 2015. Asking prices can vary widely between different examples of the same model. Our figures relate to private sales online. Dealer prices and values for insurance purposes are generally higher.

Note: Conditions listed refer to the following:
