Looks too expensive to me. Good value for any other car, but not Croma-cheap. I'd reckon £2800 would be more like it. It is 7 years old and a bit beaten up, even though the mileage isn't bad.
Having said that, used cars seem to be getting steep in general. Perhaps nobody can afford a new one, so everyone's fighting over the used ones instead.
Edit: It's not bad actually, it does have leather + sensor wipers etc.
