The C4 if far from perfect, this is true, practially the Focus was probably better, and you feel quite detatched from the road, not alot of steering feedback but the C4 was different. I probably wouldn't buy one for myself (wifes car) because dynamically it's not a patch on the 156.
I don't tend to buy cars based on how reliable someone says they are, or how much value they'll retain after 3 years, I buy cars I like. My biggest mistakes were buying a Citroen Xsara VTR and a Stilo Abarth, still no idea what drove me to part with large chunks of cash for those cars. Xsara was dire fullstop, Stilo was ok and nothing else, great value 2nd hand.
