If you were doing well in the early 1970s, a Rover P6 3500 was almost a badge of rank. But if you were doing really well, its British Leyland sister car the Jaguar XJ6 would be within reach. But was the jump from a Rover to a 2.8 XJ6 really worth it, or would you have been better saving for a 4.2?
As ‘1970 Manual Prototype Number One’, this car spent five years and hundreds of thousands of miles being developed by its maker. Today we drive it and ask: is this the zenith of the Rover P5B 3500S?
