If you can believe, I've seen an early coupe in a demo derby once. Don't recall the model year since it was probably about late 70's & I was fairly young. I don't recall it doing too well. Mustang bumpers are purely ornamental I've always said. I've proved it once on my '66 couple in a minor accident. Front one folds up due to bracket design.
