Still old cars and mileage counts for squat really, besides I'd rather have a car that's been used and not sitting around + £1500 for a 12 year old Polo is a bum deal. They are also pathetically slow, bordering on dangerous.
and your suggestion is....
A 2002 Ford Fiesta 1.25 with a decent trim level - 2002 because it's the last of the MK5s and I'm not a big fan of the MK6 at this price point. You will not find anything cheaper to run, good performance for the class of vehicle and reliable. £1500 will get you a good one, something akin to - http://www.pistonheads.com/sales/2131811.htm Whilst I think interior quality isn't a big deal for a first car, the 6n Polo (ones you linked) have an utterly disgusting dashboard nor do I think they present particularly good value for money.
That's my suggestion, I'm happy to be shot down in flames but my point was that getting excited about low mileage old cars and paying £1500 for a 6n Polo.
