£7k + for 2016+ 1.25 Ford fiesta zetec

So I’m currently looking for a car and I love the fiestas and am set on getting one. I made a post the other day similar to this and I’m just looking for a view extra opinions. I live around the south london area. I’m looking for a well maintained and good condition fiesta as I’m looking to keep it for around 4 years minimum.

The fiesta will be used for the usual town driving but also for a fair amount of motorway driving as I will be using it to commute to and from university (46 miles one way)

I was wondering what you all think of the price tag, is it too much for such a car? I’m struggling to find any good condition, lowish miles cheaper ones. Moreover what’s the most amount of miles I should look for when buying a used fiesta?

I’m also looking through trusted dealers as I’m not paying outright just yet and need the car fairly urgently.
