At that sort of price, history and condition are most critical. If one of them has got (for example) a massive folder of past receipts, etc, then that's the one to realistically go for.

If pushed to decide just from the adverts though, I'd edge more towards the Ford. Those alloys on the SEAT say 'boy racer' to me.

In addition, the Ford comes with a 3 month warranty, the SEAT with 1 month. While technically both of those are actually illegal (the selling garage is responsible for faults that happen within 6 months of sale) the Ford one does have a little more cover.

If I was going to see any of those, I'd go and look at the private sale one. Newly serviced, new cambelt and waterpump.

Though do be aware that the MOT runs out in 2 months. But you could always offer to pay for it to be tested now. Could be a very worthwhile £55.

Good luck.

Remember, when you're there, don't get attached. It's a piece of metal. If possible, take a friend who knows their way around cars.

A few (very) basics. take off the oil filler cap. Look at the underside of the cap. A failed head gasket will mean there will be a 'mayonnaise' there. Though that can also happen with cars that aren't getting much use (in which case it's being caused by condensation)

Check the depth and condition of all the tyres - the spare too. Including the make. Good condition tyres, and a good brand, means the owner has been willing to spend on the car.

Check receipts for the cambelt / waterpump and recent service.

If the owner takes it for a drive with you as passenger, wind down your window. It's amazing what you can hear (wheel bearings on the way out, etc).

Also remember : what do you think of the seller. Do they seem trustworthy ? Because you may be buying a car partly on that trust.

Finally, don't be scared to walk away if it isn't right. Too many people buy trouble.

But it 'looks' like a good honest advert.
