I know next to nothing about cars and so much more. I'm told that this is a 1972 P5B Rover. It has less than 50,000 miles on the clock.
In the 1970s these Rovers were the car of choice for many 'well to do', people. They were solid and reliable and offered a very comfortable ride.
I liked the look of them. To me they oozed class and character and they still do.
