My Xantia is the Activa V6 model. That ES9 engine is a beast. I've been told that it's usually the car, not the engine, that breaks first with those ones. But really, what I was more interested in was the Activa suspension. It feels like driving a go-kart, yet with the suspension of a Bentley, and the practicality of a hatchback. I know they were trying the same sort of anti-body roll for the DS back in the 1960s, but money was always running out (unfortunately, I cannot seem to find the pictures, I know they exist online somewhere).
I intend to keep my Xantia around for a long time. Took it to the US once, and drove from coast to coast and back again.
