The Buick Centurion XP-301 was a concept car built in 1956.
The Buick Centurion featured an electric razor-like front grill and deeply recessed headlight pods. Aside from the transparent roof, the most outstanding design feature was the television camera mounted in the rear, which relayed a picture to a screen on the dashboard to replace the rear view mirror. Another feature was a dial in the center of the steering wheel which controlled the gear selections for the transmission.
