Between me and my brother (we usually fix our cars together at his house) we had 4 xantias. No major problems with 'em apart from the lousy build quality/bits falling off and 4 hydraulic leaks (2 each for 2 cars). They all seemed to have corrosion issues between the hub and rear calipers,
2 needed the calipers removing and the broken stubs of the bolts drilling and helicoiling. Obviously the usual plastic clip breaking resulting in a view of the sky meant I always kept a new one ready to fit. New spheres all round when we bought a new car and they ride like a dream :)They do have character though, something missing in todays cars, but as I say, the fact is once you've lost fluid yer fooked and on a 160k mile 10 yr-old banger it's not all that uncommon :)
Oh yeah, the fact that they were all diesels didn't help matters, I 'ate driving diesels...
