The Bentley S1 was the last of the inline-6 models, offering classic 1950s British luxury in a package that's more understated than its Rolls-Royce sibling. It's an accessible entry point for collectors seeking a hand-built, post-war saloon.
Find one with Spotter →Typical sold price of a Bentley S1 ranges from $9,210 to $469,574, based on 263 sales tracked on Hypercars. 28 currently for sale.
The Bentley S1 debuted in 1955, replacing the R-Type and sharing its new standard steel saloon body with the Rolls-Royce Silver Cloud. It was a significant step forward, powered by a larger 4.9L inline-6 engine mated to a standard 4-speed automatic transmission. The S1 retained the traditional separate chassis construction, making it the last Bentley to feature both this design and an inline-6 engine before the brand moved to V8s and unibody construction.
Collectors appreciate the S1 for its elegant, flowing lines and its status as an 'end-of-an-era' motorcar. It offers a more understated presence than its Rolls-Royce counterpart while delivering a similar level of luxury and comfort. Because it shares mechanicals with the more numerous Silver Cloud, parts availability is better than for many other cars of its vintage.
With an average sale price around $26,000, the S1 market is accessible for a hand-built British classic. It represents a strong value compared to later V8-powered models and its Rolls-Royce twin. Well-maintained standard steel saloons offer a reliable and comfortable entry into classic Bentley ownership, while the rare coachbuilt versions from firms like H. J. Mulliner or Park Ward command higher prices.
