I paid under £4K for my manual 2004 5 door sport with 77k on the clock with 12 months MOT and 6 Months tax. Needed a VCU and a foglight and a few other little jobs so for about £4500 I have a tip-top car........ always going to get more niggles in the future that need money spending on tho.
Check VCU for tightening, Sunroof for leaks, normal smoke/knocks/rattles, All electric windows, wiper operation can be erratic, make sure 4wd system is in place and works.
There will be more just do a search on here
Good luck
