Because of this is awful lot of body roll go around the corners, when you brake gentle the front go down too much, steering feels vague and
very annoy when you put the suspensions ride height that you wish and it go back to auto level when you go over something like 10mph. The sport button on central console suppose to stiff the suspension I can't feel anything the different to me seem the C5 is spoil over Xantia and XM.
Anyone experience buy from Xantia, XM to C5 or C5 to Xantia, XM

Two misunderstandings here:
1. The lowest and highest suspension settings are for service use ONLY. Driving the car in either settings risks doing serious damage to the suspension. Intermediate height is only for SLOWLY negotiating rough ground or flood water, which is why the suspension ECU (on a C5) automatically cancels INTERMEDIATE once 20 mph or so is exceeded.
2. Changing between Sport and Normal modes simply causes the Hydractive suspension ECU to use a different set of parameters to determine when to stiffen the suspension according to: road speed, rate of turn, acceleration/deceleration. In sedate driving you won't notice any difference.
As it happens, I prefer the elegant nose of the (Mk1) Xantia to the rounder nose of the Xantia II. I don't like either the styling of the earlier C5s or Renault substitution of potentially unreliable electronics for the elegantly clever-yet-simple hydro-mechanical control system that reached a zenith with the non-sinker, non-Hydractive Xantia.
By the same token I prefer the XUD in its last pre-emissions guise - simple, reliable and fool-proof - and now that the price of diesel has dropped, 10% less fuel efficiency is a price I'm willing to pay for easy maintenance.
That said, if I came across a really nice, low mileage, well maintained, late 110HDi estate, I be very tempted to retire the Green Lady.
