A 1932 Ford and 1960 Buick received top honors at the 2023 Grand National Roadster Show in Pomona, California.
The black Ford named America's Most Beautiful Roadster was commissioned by San Antonio's Jack Chisenhall, who had been conceptualizing the build since the 1980s.
The prestigious custom car award is open to pre-1937 open-top American roadsters, roadster pickups, phaetons and touring cars.
The Ford is called the "Champ Deuce" and its sleek and simple styling was first drawn up in 2000, but the build did not begin until 2017.
