That is very close to where I live....
I've heard rumors of this car existing before... Never saw it and quite honestly, I always dismissed them.... The reason I dismissed them is a friend of mine, who also lives near where the car is located, had a 69 GTX Hemi 4 speed convertible! IIRC, that car was originally blue, but it had been custom painted in a white pearl. I always thought that there wasn't much of a chance of having two in the same area, let alone two white 4 speed cars.
There's a few guys around that area that might be involved with or know who has this car. It has me very curious.... I might make a call or two later today.
