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.

My Toyota Yaris Hybrid is perfect: small footprint yet a reasonable boot, fuel consumption between 3.2 and 3.9 l/100 km, very comfortable even for long distances. You can fault it for its mediocre uphill acceleration on the motorway. But with speed limits of 70 to 130 km/h, it still remains too powerful.
