Iconic American muscle, and an interesting read too. Learned something new today. "A panel of black slats over the rear window not only looked wicked, but helped keep rear-seat passengers from broiling on hot days. And the black-finished rear wing worked in harmony with the aggressive front chin spoiler to balance out the car's aerodynamics." - Designers really had to think through their decisions before we got AC technology perfected
