The series beginning with the Silver Ghost continued in 1929 with the Phantom II. A development of the Phantom I, the new car continued to use the by-now familiar style of Rolls-Royce engine and chassis design, improved and updated to compete with luxury cars from other British, Continental and American manufacturers.
