On Friday, the 71st annual Autorama rolled into Detroit’s Huntington Place convention center. The hot rod show celebrates car culture with hundreds of chopped and screwed rides competing for the coveted Ridler Award, including five generations of Batmobiles and General Motors’ gold-plated 1955 Bel Air Coupe, the company’s 50 millionth car. The event continues through Sunday. Here’s what we saw on Friday.
