Fiat Ducato

The Fiat Ducato is a no-nonsense workhorse that turns practicality into an artform, with a cavernous, flexible load area and predictable, car-like driving manners that make long days behind the wheel far less tedious. It’s equally at home with a tradesman’s kit or a camper conversion, offering sensible packaging, easy servicing and the sort of reliability that keeps surprises—and down-time—to a minimum.

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.
