My advice is to bring a competent mechanic to view the car before buying it. If you go on a test drive pay attention to the following:
1. Suspension rattles: if you drive over an uneven surface and the suspension starts to squeak, that might be the wishbones that need replacing (mine do on both sides
2. 78k mileage and the timing belt to be done. It seems to me that the previous owner was trying his luck. The timing belts need replacing every 36k or 3 years, whichever comes first. That could bring the price down if you try your luck.
3. Mine's a 1.6 as well, be prepared to go quite often to the petrol station. Even tough the 1.6 is nimble enough (for me), it really drinks, having to carry that heavy body around.
4. Also when test driving it, if it feel slugish it may be the Air Flow Meter (MAF), that needs to be replaced, and ONLY buy a genuine Bosch ones. The ones on ebay are ****, and as Dave (theredx) told me, you'll soon want to put the old non-working one again.
5. Oh and check the oil, some drink oil and some don't. But if you don't take care of it, she`ll make your life a misery
6. You can find the skirts and the rims fairly easy I'd say, sometimes there's loads of them for breaking, just have to look. The usual ones go on donedeal and gumtree.
