Azur, don't forget Italy. I believe around 12,500 were sold there. Rare to see any these days, but they do exist, though no idea how to find out about actual survivors. There is a small but enthusiastic Rover/MG supporters on a FaceBook group.
They are just as keen on other Rovers too like the 200 range and 400 etc. Prices of ones out there are usually a lot higher than here in UK.
