After 60,000 miles relativly trouble free driving -comfortable, roomy and powerful enough and 40mpg. apart from the road noise, my 2 big problems are:
(1) the drivers seat which has NO lateral support (I am not particularly thin!) and:
(2) the fixed toe-in that causes the rear tyres (£120 each) to wear bald on the outer side with none on the inner -front tyres last about 30,000 miles with my driving but the rear were almost bald on the outer side, untouched inner, by this tme. On the Xantia est. I did not have to replace rear tyres for 90,000 miles.
No support from the dealer on this front.
