We had a ZX, which is mechanically pretty similar – same as a 306 or Xsara. No hydraulic suspension.
Electrics were a bit ropey – only 5 fuses or so for the whole car, clocks worked as and when they felt like it. It was galvanised but failed it’s MOT on rust in the seam in front of the petrol tank, under the rear seats. Seam sealing seems pretty poor – brush on stuff rather than the thick squirted in stuff VW use. General build quality was poor – sunroof leaked, things rattled.
The old 1.9D (XUD I think) is steady but will last forever.
TBH I’d look for something else – I bought the ZX for naff all with full service history, an interor that stank of fags and dogs, and not a great deal of miles on the clock. We ended up scrapping it at something ridiculous like 85k because it wasn’t worth fixing.
I’d go for MK1 Focus or late MK3 Golf if you want something with a reasonable “image” for a grand. If you really don’t give a monkeys about image, you can get a Daewoo Lanos for bugger all with very few miles. Interior is typical far eastern economy car horror, but you tend to get aircon and the mechanicals are Vauxhall based.
