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.

...the best electric car we've driven so far. Trouble-free, safe, tidy and easy to use.

The German predecessors (the Wolfsburg group) can be completely forgotten!

A car that could have been brilliant, ruined by technological dogmatism. Ninety‑five percent of this car’s problems are between the windshield and the steering wheel. The positives are undone by a botched implantation of technology at all costs. Basic functions are hard to access, buried in menus, and the constant, useless warnings and alerts make the experience frustrating and wreck the overall ergonomics. Add recurring issues with the door‑locking system that the dealer can’t fix after several visits, a range far below what’s promised, and a collision‑avoidance system that randomly takes dangerous initiatives, and I can say this is the worst car I’ve ever bought. After several months, I deeply regret this purchase.

The onboard tech (tablet) takes too long to learn. It distracts from driving. Not suitable for the nearsighted — the tablet’s distance from your eyes basically forces you to wear trifocals. Letting off the gas slows the car, but it’s overly sensitive and you need time to get used to it. The buzzer for exceeding the speed limit is very annoying, and the system notices changes in road signs late. In short: driving it is stressful.
