What rubbish! Why do you fall for this cliche? Like any other generalisation, flawed to extreme.
I had 4 DSs, NONE of whom had problems- except with the pillock who crashed into one and wrote it off (it was STILL drivable even bent up!)
The DS suspension had a false poor rep, I suspect because it was so different. A well engineered system that worked extremely well.
Like all cars, if it wasn't maintained it would fail- but no more than yer Ford (no....much LESS!)
I'd guess any DS now will either be needing serious rebuilding or be expensive. (There's one I saw, totally rebuilt, going for £75K!)
They are old beasts now of course.
I drove a borrowed one for a friends wedding about 12 years ago (when I had my Ser 3 LS) and thought (the DS) was a bit of a truck.
But then, much is, in comparison with a Lex.
