It's a Wartburg 311 Convertible from East Germany. "In December 1955, AWE introduced the Wartburg 311. [...] the Wartburg was well built, with body-on-frame construction. It was powered by a 900cc, 3-cylinder, 2-stroke engine and had a 4-speed transmission. Top speed was about 70 mph. [...] Wartburgs were offered in eleven configurations, including sedans, coupes and station wagons and were ultimately exported to 55 countries. While its styling was reminiscent of a GM car from the early 1950s, the Wartburg was actually a fairly good-looking automobile. [...] Americans bought a total of 1,215 Wartburgs. There are a few still running today. Probably the biggest collection belongs to Californian Victor Birschansky, the owner of sixteen Wartburgs, including a 311 convertible that he drives."
