I saw the car in the UK at the Goodwood Festival of Speed one year, and then was surprised to see the same car turn up in my backyard a few months later.
The car was at (and the photos in the ad were taken in front of) Hall Fabrication, a high-end Cobra restoration shop in Benecia, CA, between San Francisco and Sacramento (and 20 minutes from my house):
Hall Fabrication & Racing, Inc.
Note that this car was built for light weight, and as such, is fitted with a 302 (an extremely mild 302 at that) rather than an FE motor, MK II tail section notwithstanding.
It's certainly the quietest GT40 I've ever heard, and that, plus the open top, would make it a very enjoyable road car, I think.
A friend owns another of the Safir Mk IIs with the removable tops; his has an all-aluminum 496 inch FE motor with 11,347 horsepower, and straight pipes.
Not a very enjoyable road car. :laugh:
