Which is why sometimes you need to play it safe and get cars with a reputation of reliability.
That's fair enough.
However - no one supermini in particular (apart from the Fabia, which always seemed to do well) has a significantly better reputation for reliability than any one other, so tarring all the French or Italian cars with a brush is a little unfair, unless you're prepared to do the same with the others.
Using personal experience is all very well, but there are limitations. Saying that you know one girl who bought a Ka because it's cheap is in no way a suitable grounding to suggest "it's a woeful pile of misery, don't go near them". Particularly as it's
mechanically identical to the Ford Fiesta, to which you say "cheap insurance, good reliability...it's very hard to go wrong". It's either one or the other - they're both crap, or they're both good choices.
The moral of this story, particularly given your friends' experiences of exploding Saxos (for the record: not a car I'd choose, but then I knew people back when I was in high school with them and they never had any problems), is that with
whatever Liquid buys, he buys on condition and service history rather than mileage and badge.
Stealing Famine's words from another thread:
a car that has run 30,000 miles in first gear at redline for a 2 mile journey every day and badly maintained will be terrible, but a car that has run 300,000 miles driven sympathetically and maintained correctly will be fine. Mileage is just a number and not a very relevant one.
Even the Fabia mentioned could be no good as a used choice if it's been driven flat out everywhere and never topped up with oil (unlikely, but to illustrate my point), but a supposedly unreliable Clio with 250,000 miles on the clock might be fine - and frankly, any supermini that racks up huge mileages and is still on the road was probably put together properly in the first place.
Or to sum up: Whatever car you buy, buy one that has plenty of evidence of being loved, and if you're buying privately, run a mile if the owner is in their teens.
I'd also personally recommend going for a trim level with as little equipment as possible. You don't really need aircon or leccy windows in your first car. Electrical stuff is most likely to go wrong, it's just something else to potentially waste money on.
