For much of its early history, BMW wasn't known for making cars that could be accused of getting your pulse racing. Post-war financial difficulties meant the company churned out sedans and microcars like the Isetta to get back on its feet, which made the 507 roadster an outlier in the BMW lineup. This 1957 507 is about as rare as it gets — one of only 34 Series 1 507s produced, and with a fully documented history from new. Nearly original, the paint and a swap from the original front drums to disc brakes are the only changes in 60 years. A lovingly maintained driver, this car deserves an owner willing to keep putting miles and memories on this classic.
