The only branch of this company I could find locally to me was this one, not far from Kings Cross station in Central London. Stratstone's appear to deal mainly in Jaguars and Daimlers. They're quite a large company with branches throughout the UK. Amongst their former customers was no less a personage than Winston Churchill. Stratstone are part of the Pendragon Group.
