Hi Brian,
I had one for a few years, I loved it. You can genuinely get 50mpg out of it not much difference how you drive it from what I saw. It is the N47 engine so either make sure the chain has been changed or it has been serviced every 10k miles. Also to look out for is the clutch and also usual dpf, although the dpf or chain never gave me any problems and I sold at 156k. After I sold it the clutch went.
