The 1957 BMW 507 Roadster Series I first came into existence from renowned European car importer Max Hoffman stubbornly convincing BMW’s big brass to sidestep production on its customary microcars to instead take a stab at designing a hybrid speedster model. The renowned European auto importer envisioned a car that could straddle the line between a higher-end Porsche 356 Speedster and a Mercedes-Benz 300 SL, along with the sensibility and sophistication of an MG. The 507 Roadster extracted components from both the BMW 502 and 503 series — the centerpiece being the 3.2-liter overhead-valve V8 engine. Having only known four owners over the course of its life, this particular 1957 BMW 507 Roadster Series I has only 73,000 kilometers on its speedometer and is currently up for auction at RM Sotheby’s.
