There are three tiers of Jaguar Heritage Experience. The 'Jaguar Experience' ranges from £95 to £250 with opportunities to passenger in and drive some Jag icons. It includes a quarter of an hour driving a MkII for £135 or a 30-minute passenger ride in an XK150 at £95 for example. There's also the chance to drive selected pairings; 60 minutes driving split between six- and 12-cylinder E-Types costs £250. Jaguar promises its seasoned professionals include some 'recognisable faces from the world of motorsport' too.
