1969 Yenko Chevelle all original under 5K miles

[newbie]

I spoke with a buddy today who says he came accross a gentleman with a 69 Yenko Chevelle, an early Yenko campaign car with all of it's original equipment down to the tires. It apparently has been in a climate controlled environment since 1970 and has under 5K miles on the odo. Owner has documentation and the car even has the "win stickers" still on the back window. He claims the car is one of three built and that the other 2 are known to have been destroyed. Car is blue with white stripes. Please contact me if you can shed any light on the "one of 3" claim or if you have any interest.
