It all started with a lunch invitation from our friends at Hagerty, those nice insurance people, at the Goodwood Revival. The guest sitting across the table looked familiar, and sure enough it was British actor Chris Barrie, a veteran of the Red Dwarf sci-fi comedy series who American viewers might also recognise as Laura Croft's butler Hilary. It turns out that Chris is a die-hard petrolhead with a particular affinity - bless him - for old Jaguars. This got us thinking, and that's how a couple of months later we found ourselves on a wet, cold Welsh hilltop with a 57 year old racing car noisily barking at the tranquil countryside.
