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.

Nissan Interstar

The Nissan Interstar is a sensible, no-nonsense panel van that puts practicality front and center, with a cavernous load area and a durable feel built for daily work. It drives with surprising composure for its size, keeps running costs modest, and feels like the kind of professional tool that prefers reliable service over flashy showboating.
