As long as it's been well serviced then I shouldn't see it to be a problem. It sounds like it's cared for 🙂 but definitely find out why the owner is selling it.

Hi Richard all modern diesels have dpfs now I'm afraid. If the car doesn't do long runs then the dpf can clog and worst case scenario it'll have to be replaced which will cost around £1000+
