One of only seven known to be built, this Mk III coupe was intended as a road-going alternative to earlier racing-bred GT40 models, like the original Mk I and 427-cubic-inch, Le Mans-dominating Mk II. Due to its street-legal intentions, the Ford GT40 Mk III boasted revised bodywork that allowed for some luggage and new headlights, along with a redesigned interior with left-hand-drive and a shifter in the normal, center position.
The Mk III wasn't very popular when it was new in the 1960s, in part because it looked different from other GT40 models and because it was pretty expensive, but that just means it's an awfully rare gem today.
