I've heard of springs going on quite a few cars - Yet another reason to buy a Citroen, I guess.
Perhaps I'm lucky to only have springs on the front, but I suspect my next car will be a very early (maybe 51 reg just so the tax is cheaper?) HDI Citroen C5 Estate since their reputation for scary technical complexity, combined with an utterly bland image and lack of design inspiration has sent second-hand values for what is essentially a comfy, incredibly generously equipped and massive car through the floor.
And from what I've read, there are complicated electrical problems, but they don't seem to be as hellish as the Lag IIs, and any fears over the suspenson are likely vastly overstated, since like the Xantia beore it it's actually a very reliable hydraulic system that given decent maintenance should cost less to keep in decent nick than anything with sprung suspension!
