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.

Renault Symbioz

The Renault Symbioz feels less like a traditional car and more like a rolling living room that's been told it's allowed to drive — its flowing lines and minimalist cabin are pure concept-car theatre that teases the future of everyday transport. For buyers with an eye for design and a taste for tech-forward ideas, the Symbioz is an alluring vision of what Renault could offer tomorrow, even if it's not yet a model you can park in your driveway.

I've been driving the Symbioz Full Hybrid with the iconic trim for 3,500 km. I test-drove both cars. I think the win goes to the Symbioz. Good quality at a family-friendly price. Unfortunately the Opel is simply too expensive. Strangely, what never really gets mentioned is that the Symbioz's suspension is absolutely superb.
