I also drive a citroen XM 2.5 td and find the ride very comfortable especially on the Argyll roads(more holes than road)

Oleopneumatic suspension= magic carpet ride

.
Adjustable ride height,sport setting(firmer).
AND its fully RUSTPROOFED.
On the down side...
Working on it is a right pig
For exampleHad to change the engine sump. To get the sump of you have to...
REMOVE:-
ECU box from inner wing
A/C compressor
Top & bottom right engine mount buffers
Auxillary belt & tensioner
Cam belt covers top &
crankshaft pulley to get to bottom cambelt cover
Lower right engine mount buffer bracket
drain cooling system & remove turbo intercooler
Lower rad hose
pressure regulator/main accumulator
Fuel filter & priming pump
radiator expansion bottle
fly-wheel cover plate......
Just so you can get to the 2 nuts & 22 bolts that hold the sump on & remove the sump.

Refitting is a reverse procedure BUT to refill the cooling system you kneed a header tank to go onto the expansion bottle otherwise you get air trapped in the system.
FUN EH!
And why did I have to change the sump?
A deer's antler made a hole in it

I love my CARLTON even more now
