It was a very innocent time. I bought this car at a dealer auction ( thru a friend's dad) for $1030.00. There were 6 Shelbys there that day...4 Black/Gold Hertz's, 1 really beat up 67 GT500, and mine. 531 was in the best shape of the 6. They all sold in about the 1K range...Wish I knew the serial #'s of those cars. Here is a pic of the engine in 531
