The central suspension spheres have been replaced - at a cost of £130, the other four spheres were replaced when I bought the car.
The remote control for the central locking needs a bit of paper in the key housing to enable it to work!
There is a bad vibration between 65-75 MPH which repeated wheel balancing has not solved - I wish I could get to the bottom of this.
The car is very comfortable, economical (I get 43 on a motorway run cruising at 80-85 MPH, 39 commuting in stop start traffic and 31 when towing a caravan.), reasonably roomy, not as expensive to run as its reputation would make you think, tows a caravan effortlessly and performs well.
The judder from the front was solved on my xantia by removing a rust build up between the disc and hub, also having the tyre pressures checked more frequently helped.
