The GT40 may be the more interesting of the two. It's the last of 12 GT40 chassis built by Ford for 1967, the only year Mk. IV GT40s raced because of rule changes for 1968. And when it was built, it was really just a chassis built as a spare for the cars Ford took to Le Mans. The chassis made its way to private owners in the intervening years, one of whom collaborated with a former owner to finish it into a complete car. It has the correct dry-sump 427 V8 making about 525 horsepower and a correct 4-speed manual transmission. The project was finished in 1987. Of interest to potential buyers, the car is now eligible for participation in FIA-sanctioned vintage motorsports events.
As for the Cobra, it's still quite rare as one of 260 units. But it's really special for its originality. It was taken to 13,000 miles by its original owner, and the second owner only added 6,000 more before parking it in a garage in 1991. It was never modified, it has its original paint, wheels and steering wheel. And despite sitting for so long, the auction house reports the car was able to be fired up without too much difficulty or repair. The car was also featured on Hagerty's video series The Barn Find Hunter.
Both cars will be auctioned at the Amelia Island auction on March 9. An estimate for the GT40 wasn't given, but the Cobra is expected to bring $1 million to $1.3 million.
