Advice on e90 320i

A mate is looking for a cheap run around and sent me a link to this:

http://www.adverts.ie/car/bmw/3-series/bmw/9745059

The car is in Navan and he lives in Waterford so before he makes a long trip.....Any advice on what to look out for or any future potential problems? Any advice is much appreciated...

Coils, injectors, major oil consumption (in particular on a colleagues 06 320i SE). Worth keeping in mind, if viewing.

Thanks Ciars I passed that info on....
