Early '70s on my way to the French GP at Cleremont Ferrand when a Healey 3000 went tearing past hotly persued by an Alpine Renault. Flashing lights, siren going and painted light blue with " Gendarme" written on the side!! First time I'd seen one, and boy did it look good with all that neg camber on the rear. I never saw them again so no idea who won!!
