To figure out where your question is going Daz, a high Km 2nd hand vehicle is not so much of an issue if the car is doing Sub 10,000kms a year.
of course it depends on the quality of the vehicle in the first place
keep an eye out for expensive service items like Timing Belts

if you plan on using it as an Uber, well that's another story -or Thread
