Old Classic

Cars that used to look huge in their day now look very small against the cars of today. Although this shot makes the Rover look quite large it looked small parked next to a medium size family car.   I saw its elderly classic owner come out of the supermarket and wonder if he's had it since new. Any ideas how old it is?
