Yet another classic convertible willed into existence by NYC importer Max Hoffman, this 1957 BMW 507 Roadster Series I was a large departure for a company that at the time was making microcars for the masses. It was built primarily from parts borrowed from the 502 and 503, including the 3.2L V8 engine. This particular car has seen only four owners over the years, including one who kept it for over 50, and retains its original interior and engine, with just over 45,000 miles on the odometer. It's also one of only 252 ever made, making it both attractive and rare.
