1938 Mercedes-Benz 320 Cabriolet B

191191roadGermany
Engine
Redesigned inline-six, over triple the output of the prior 2.9L side-valve unit

A 1938 Mercedes-Benz 320 Cabriolet B, one of only 5,189 model 320s built at the Mannheim factory between 1937 and 1942, and one of very few surviving cabriolet examples with continuous, documented registration history. Originally owned by HRH Princess Sibylla of Saxe-Coburg, mother of King Carl XVI Gustaf of Sweden, the car remained in Swedish royal family use throughout the war years. Factory production records were destroyed early in the conflict, making authenticated survivors exceptionally rare. The car has undergone a comprehensive recent restoration to high standards.

This car's public record is built from its auction and competition history. Register your ownership and privately add your own records to make it a verified Legacy Metrics passport — provenance that backs your car's value at sale and gives your insurer evidence to price against.

Each chassis record is compiled from public auction archives and links to its source material. Ownership, competition and maintenance entries are extracted from those catalogue listings by an LLM, which can make mistakes — please contact us with any corrections. The summary is Legacy Metrics’ own writing; we do not reproduce catalogue text.

“Full” and “partial” documentation labels indicate how well each entry is corroborated in the underlying sources, not an audit of the car’s physical paperwork. Names of recent or living owners are withheld for privacy.
