Some cars whisper history. This 1957 BMW 503 Cabriolet sings it. One of only 139 cabriolets built between 1956 and 1959, this Series I example blends rarity, elegance, and mechanical artistry into a single unforgettable silhouette.
1957 BMW 503 Cabriolet Design and Legacy
Styled by Albrecht von Goertz, the 503 was BMW’s answer to American demand for luxury sports cars. With aluminum body panels over a steel ladder frame and a hydraulically operated convertible top, the cabriolet version offered open-air sophistication. This example, chassis 69146, was delivered new to Frankfurt and has since passed through some of the most respected collections in the U.S.
Restored With Precision and Care
During its time in Palm Springs, the car received a cosmetic refresh that included a repaint in its original Papyros white and a full interior re-trim. Chrome bumpers, central kidney grilles, and upward-sweeping side trim add visual drama. The navy blue convertible top contrasts beautifully, and the hydraulic pump was replaced in 2012 for smooth operation.
Power and Performance From a Refreshed V8
Under the hood lies a 3.2-liter OHV V8 with aluminum block and heads, twin downdraft carburetors, and pushrod-operated valves. Overhauled in 2012, the engine delivers refined power through a column-shifted four-speed manual transmission. The car also features independent front suspension, a live rear axle, and power-assisted finned drum brakes.
Rudge Wheels and Driving Confidence
Rudge center-lock wheels were added during the mechanical refresh, refinished with body-color centers and secured by two-eared knock-offs. Avon Turbospeed tires wrap each corner, including the matching spare. Braking confidence comes from a rebuilt booster and new master cylinder.
Interior Elegance With Vintage Touches
Inside, navy blue leather with pale gray piping covers the bench seats and door panels. A Blaupunkt push-button radio, lockable glovebox, and power windows add comfort. The ivory four-spoke steering wheel fronts a body-color dash with VDO gauges, including a 240-km/h speedometer and 6k-rpm tachometer.
A Collector’s Journey Across Time
From the Blackhawk Collection to Bob Pond, Ron Lauder, and now Houston, this 503 Cabriolet has traveled through time with grace. It comes with a BMW Classic certificate, a book of refurbishment records, and period-correct accessories like a jack and hammer.
Summary
The 1957 BMW 503 Cabriolet is more than a rare open-top classic. It’s a testament to BMW’s postwar ambition, restored with care and driven by a refined V8. With timeless styling and mechanical integrity, this cabriolet offers a rare chance to own a piece of automotive history.
