If you value relaxed comfort, clever practicality and a car with personality rather than pretence, the C4 is a charming, sensible choice — and it won't make you miss the usual hot‑hatch theatrics.

A very comfortable car, but with a flaw I noticed: very high door sills, which you really feel when getting in.

It won’t set your pulse racing on a back road, but it will make school runs, commutes and grocery hauls feel pleasantly civilized — a reliable, slightly posh companion for real life.

My wife and I have been driving a Mercedes W247 200d for seven years now, with 93,000 km on the clock. The car is very comfortable even on long trips and economical. At the last service the pads of the electric parking brake were replaced; otherwise no repairs. We love this car.
