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.

Mitsubishi Grandis

The Mitsubishi Grandis is a no-nonsense MPV that hides a surprisingly sleek profile, making family duty look almost stylish. It’s spacious, easy to drive, and built to shrug off daily chaos, though the cabin feels dated and it prefers a relaxed cruise to any hot-hatch antics.
