Reliability made the marque
The 40/50 H.P. established Rolls-Royce's engineering claim. Collectors buy the chassis: original coachwork, unbroken build record and usable mechanical condition separate seven-figure Edwardian cars from later rebodies.

Estimate band for good road cars. 42 documented sales since 2019 plotted below.
Band and axis shown in USD. Sale positions use indicative fixed-rate conversion to USD; sale readouts retain recorded currencies. USD, before inspection. Exceptional original-bodied Edwardian cars can exceed the band; later Springfield cars and compromised or formal-bodied examples can fall below it.
Instrument calibration for this file is in progress — the terminal above reads the documented record directly.
Two documented public sales are shown as evidence of the spread, not as direct comparables for every Silver Ghost.
Overview
By 1906, Rolls-Royce was building several low-volume models whose parts changed constantly. Claude Johnson proposed concentrating the company on one expensive car; Henry Royce answered with the 40/50 H.P. and its smooth six-cylinder engine.
The twelfth chassis, 60551, carried silver paint and fittings and the individual name Silver Ghost. Johnson used it in reliability trials, while Royce continued to revise engines, transmissions, brakes and chassis details through the production run.
British manufacture moved from Manchester to Derby in 1908. Springfield production served the American market from 1921 to 1926, with local chassis details and American coachwork. Those differences, plus later rebodies, make chassis-level research essential before valuation.
