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.

Fiat Qubo

The Fiat Qubo is a compact, boxy people carrier that makes daily chores feel less like a battle, with a surprisingly roomy interior and clever sliding doors that make loading kids or shopping embarrassingly simple. It’s not trying to be a sports car — instead it’s a sensible, easy-to-park city partner that rewards practicality with low running costs and a cheery Italian twinkle.
