I paid $500 for my '96 850 T5 wagon a couple of years ago, and spent 3 times that on it now. Things like tyres, batteries and brakes need to done on almost any car you buy at some stage - I fitted a battery when I got it, tyres a few months ago and haven't done any brake work yet. I got it needing a radiator, and did a few other things to get it road worthy.
Pros - comfort, power, economy and load space.
Cons - it has a factory sports suspension package, I find the ride harsh and a bit low, but comes into it's own when pushed hard. Cheap and nasty hard plastic, noisy, breaks easily and just cheapens the quality. Some things are easy to work on, others not so, and the turbo doesn't help there, not much space around the engine.
I'm pretty pleased with it compared to what I would've got with the same money on another more popular brand. People are scared of Euro cars when something goes wrong, and the prices plummet. I wouldn't want a 21st Century Euro car, but 20th Century they were solid, reliable and very soundly engineered.
