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.

I've been driving the VW T‑Roc for a few months now and I'm totally satisfied. 🚗 The higher seating position gives me a great feeling of security and the visibility in city traffic is excellent. I especially like the modern infotainment system — everything works intuitively and quickly. On the motorway it feels very calm and stable, even at higher speeds. Overall a great car that's a lot of fun and still economical.
