I've started looking at Fiesta MK2 XR2s.
I really like the car, a couple of friends of mine have always had them - and they seem to be crazy fun they look brilliant.

Has anybody got any tips for me, to aid me in my searches? what to look out for, what needs changing at what miles, etc?

What sort of car could I get for around £700? (that's the car budget, although there is plenty to be spent after for zetec engine )
