Very interesting. Rear engine Mustang was unexpected. Too bad most prototypes get destroyed. Thank You for sharing the video.
Yep! My Dad & I (owning a salvage yard in Coachella Ca.) were hired by Ford DST in Palm Springs to destroy a several prototypes, a few concept cars and other retired show circuit cars, circa '79. Most notable "Concept" cars we destroyed were a pair of VERY early ESCORTS. No glass (black-out plexiglass or similar) also no interiors installed yet, these "Escorts" were just hunks of junks that moved on their own power. Interesting note was the powertrains were Mitsubishi's out of some Dodge Omni's.
Otherwise, EVERYTHING gets crushed. Engines, Trans, Brakes, Glass Wheels & Tires. About the only things they did allow us to keep were the drivetrains from the Escorts, because they were not "Ford", that was about the only exception. The other vehicles were already currently in production that we crushed. Besides the Omni powerplants, we were given scads of seats and trim parts they pulled out of show cars that were touring the country. Periodically, they would repaint them and change out the trim options so these kinds of parts were then considered surplus. Tough to feed brand new Mustangs and F-150's into a car crusher...but FUN as hell too! I was 18 at the time.
