I wonder how a hydraulic suspension would fare if produced by today's technology and quality standards. DS has a flying carpet ride feel to it and even the most upmarket cars of today can't reach that.
Unfortunately it's plagued with electrical problems. When you plug in an iPhone into the USB charger port, the navigation and heating crashes. The ECU and several CAN bus controllers have been replaced and it still does it. Plus the alternator exploded. Fortunately all under warranty but for a car that has been on the road for 4 months, it's spent 6 weeks in a garage.
I drove a 1992 V8 110 county a few years ago. Best car I ever had. Didn't go down well with a young family though, all the climbing and stopping for petrol, so I had to give it up for a people carrier :(
Then again I have a FIAT (Fix It Again Tony) with a MultiJet engine which has been hellishly expensive to keep alive so today's technology and quality standards are debatable.
