I spotted a CX break on my travels today funnily enough, it was a red one with many battle scars but the suspension appeared to be functioning perfectly as every other car on the A1068 at the time (around 10am) was bouncing around, in and out of the undulations left by decades of pit shafts and a tightwad council. It sounded sweet too and the driver had a massive grin on his face as I extended a thumb in appreciation of his "playworn" but clearly still very usable 1985/'86 big Citroen.
I didn't want a new Xantia when they were actually new, time hasn't changed this situation.
