FWIW, there is another sort-of-real MK1 GT40 running around the S.F. Bay Area. I have seen it from a distance several times (the owner has a bad habit of leaving car shows just as I arrive), and finally got a chance to look at it up close and personal at a Nor-Cal Shelby Club track event back in April.
It is VERY scruffy. The body is unpainted and ill-fitting white fiberglass, with UK number plates painted on. It is equipped with BRM wheels, has original Girling brakes, and the interior looks like it has been lived in for several years. The wheels are covered in brake dust, and it leaks oil and fluids from every place except the taillights.
The owner is a very nice gentleman, who explained that a friend of his had some sort of ties to FAV, and when the GT40 program was tapering off, sometime in the late 1970s I think, he was able to buy a complete, un-numbered tub, and all the bits necessary to build a complete car. He built the thing himself, and thus it's not considered a 'real' GT40, but it was built entirely with original parts. So in many people's eyes it could be considered a 'real' GT40, as opposed to a 'kit car'.
It has an FAV build plate, with a miles-long VIN stamped on it, one assigned by the California Highway Patrol (or by the California Department of Motor Vehicles--I forget which government entity issues chassis numbers). Apparently this guy's friend completed the car and drove it for years in the UK, then sold it to him, and when it arrived I guess it had no chassis number, so to register it and title it, it had to have a new number generated out of thin air, which didn't follow any of the original conventions.
To his credit, the current owner DRIVES the car, both to car shows and to track events (he ran for awhile at Thunderhill, but then something broke and he called it a day).
What's really special about his car is the California license plate: "66 GT40".
How many people do you think would love to get ahold of that!?
