Why it matters
The GT40 Mk III was Ford's planned road-going version of the car. The cost and complexity of converting full race chassis led Ford to cancel the programme after only seven cars were finished, which makes it one of the rarest GT40 types.
How rare is it?
Six separate kinds of rarity – never combined into one number.
Each kind of rarity is rated separately and never combined.

02Production & history
Production
Every figure says what it counts.
| What is counted | Figure | Basis | Status |
|---|---|---|---|
| Total model productionMk IIIs built (M3/1101–M3/1107); 3 sold to customers | 71,2 | Factory production | Factory reported |
Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.
History
In late 1966 Ford's Dearborn headquarters commissioned 20 late-production GT40 chassis for the planned Mk III road car programme. The chassis came from the original batch of roughly 105 built by Abbey Panels in Coventry. Converting full-race chassis to road specification pushed the projected price so high that Ford cancelled the project. Seven were completed as Mk IIIs, leaving 13 unused chassis.
One of the unused chassis, P/1085, was sold in 1969 as a rolling chassis and stayed uncompleted for decades. It was built up in 2009 as a competition-specification car with a 5.0-litre Ford V8, and is described as the last GT40 numbered in sequence by Ford Advanced Vehicles.
