A 1966 example of the Ford GT40 MkII is heading to auction in January—and it’s not just any example of the already ultra-rare car, but the “most original” one.

Eleven MkII GT40s were built, and just nine survive today. Of those, only three were built with the lightweight chassis; that trio includes the one currently going up for sale, which is also said to contain the most original parts, after restorations of the others.

This 1966 GT40 MkII has its original body, chassis, and roof. The suspension is unique to the lightweight versions of the GT40 MkII, and it was built by Shelby American at its famous factory near Los Angeles International Airport. The example going up for sale now via Mecum is known as the XGT-3.

“There are other MkIIs which have been fabulously restored to original configuration, but only XGT-3 is in that original condition still,” GT40 expert Ronnie Spain told the auctioneer.

The 1966 Ford GT40 MkII is powered by a 7.0-liter V-8 engine that made in the neighborhood of 485 horsepower. It sent that power through a 5-speed manual transmission. The example up for sale is painted red and was owned by the Ford Motor Company until 1977, when it was sold to the first of four private owners.

The example actually began as a FT40 MkI, before it got a series of upgrades. It never raced, instead serving in a backup capacity. Its sibling cars, of course, became famous for winning the 1966 24 Hours of Le Mans in a first-, second-, and third-place finish, dethroning Ferrari in the process and becoming the stuff of automotive legend. Ford’s ascent has been documented in many a book, in addition to television and movies, like 2019’s Ford v Ferrari.

The modern Ford GT, which began production in 2004, is an homage to the GT40, made to celebrate the automaker’s 100th anniversary and one of its greatest achievements.

Mecum does not give an estimate for the 1966 Ford GT40 MkII, though a seven-figure price in the multiple millions of dollars is to be expected. The auction takes place on January 16 in Kissimmee, Florida.
