Citroen C5 Aircross

The Citroën C5 Aircross feels like a sofa on wheels, delivering a calm, floaty ride and clever packaging that makes life with luggage and kids noticeably easier.

Cars like the C5 Aircross are probably one reason why Stellantis is almost bankrupt — or already is.
Uncomfortable and completely unsuitable for long-distance driving.
Huge on the outside, small on the inside.
Extremely uncomfortable seats, poor infotainment, very bad driver aids (360° camera, cruise control, lane-keep assist, navigation… are really awful), confusing, poor road manners, loud engine and noisy wind.
I can only hope that I’ll never again be forced to drive this vehicle.

I find the Citroën better suited to my daily driving — more comfortable and efficient, with a softer suspension compared with the firmer Toyota Cross.

Mercedes B Class

The Mercedes B-Class is a smart, grown-up compact people carrier that dresses everyday practicality in a near‑premium polish, perfect for buyers who want comfort and a classy badge without the theatrics. 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.
