My mate owns a 53 plate Fabia vrs he got it with 50k miles and got it mapped and a few other bits and made 182bhp and 311lb ft. It's now on 160k miles he gives it constant abuse I've been in it chewing the arses of mk2 rs' and wrx imprezas ect, still on original clutch and turbo. Bomb proof apart from the shitty interior that's falling to bits, door locks and windows don't work, seals leak ect but all round impressive car.
I'd imagine you'd get an old one within your budget
