Come for a drive in two models that were crucial for Rolls-Royce’s success: a 1926 20hp and 1976 Silver Shadow. What do they share? If you fancy more potent performance, the awesome Bentley Arnage is a temptation explored in our Buying Guide, and Bentley’s vintage flagship, the mighty 8-litre, is sampled in California. If it’s sunshine you want, try the gorgeous 1980 Corniche, while other diversions take us to a Rolls-Royce 25-30 and a road test of a Bentley Flying Spur. Variety rules!
