Mark's neighbor was an attorney that owned 3 Shelby Stangs, acquiring each as payment on cases, and this was the one he drove the most and damaged in the early 80's, and then parked it in the warehouse over his office. Once it went into the freight elevators and into that warehouse it was off the radar... til the attorney finally mentioned selling it to the single person that could reunite it with the once teenage neighbor kid
The original 428 was blown early, and replaced with a 390, but the sale went through at 25 thousand to Mark, because he'd known the seller since the 80's and the seller knew it was going to a good home finally
