Having spent the last decade driving BMWs and Mercedes, the C6 has been an eye-opener. It's criticised for being 'wallowing' and for poor fit and finish, but while a few components are borrowed from lesser models (something of which every accountant-run manufacturer is guilty these days), the ride damping changes to suit the road - ranging from merely 'good' to 'unbeatable' depending on how and where you're going - and the quality of cabin plastics is a match for any 5-Series or E-Class. I do have three complaints. The first is that the magic carpet ride suffers over broken tarmac at low speeds - a longstanding trait of Citroens. The second is that the navigation system is an antique. The third is that the economy is less than impressive. My S320 CDI would average 40mpg and deliver 600 miles from a tank; the C6 averages closer to 30mpg and needs refilling every 400 miles. Having said that, the 20,000 mile service interval means that so far my only running costs have been tax, insurance and fuel, and with Citroen now in WhatCar?'s top ten list for reliability, I don't expect that to change. So other than very minor points, the C6 makes a first class express, its seating position being far more comfortable than that in the S-Class (which used to give me pains down my right leg on long journeys), and the fact it's the antithesis of German cars makes ownership all the more enjoyable. You're not likely to be trying your key on the wrong car in a busy car park!
