Depends on how much it is but as with what everyone else has said you will need to know what works been done so far, mines a 2013 and solely used on 90 mile motorway round trips since I bought it, now on about 140k.
So far I had the radiator and egr changed, clutch and flywheel just been changed along with cambelt and some other stuff so I've probably forked out about £2/3 grand on it over my ownership.
With that mileage you'd want to check if the clutch and flywheel, suspension and bushes, turbo been changed will probably have had 2 cambelt/ waterpump changes by now or may need one shortly.
You'd have to check when most of the above was done.
If it's from a main dealer and then think you get a years warranty so may be ok.
Me personally if it was just a runabout for a bit until you can order your new car, then I'd get something Jap like a Toyota for a couple of grand, cheap parts and loads of scrappies about for them and not a lot goes wrong with them and then just trade it in when time comes, might be boring or less jazzy but the money saved will be more welcome in these times.
