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 electric drivetrain pays off, especially in turbulent times like these. EVs have left their teething problems behind and now also offer good range.

It's a technologically advanced car, but somewhere along the way VW forgot the pleasant cabin and the comfortable ride. It IS a VW — and that redeems it.

The ID.4 is a bit pricey, but very pleasant to drive. Its winter range could be better — then again, that's a problem all EVs are facing right now.

An ID.4 with 340 hp is not comparable to the Aiways U5! The U5 only has 204 hp! The ID.4’s boot is too small, rear legroom is too tight, no frunk, and it’s a bit confusing…

I have an ID.4 GTX and it drives like a dream — loads of extra power, sits well on the road, high seating position, quiet. I can see other cars have bigger screens, but mine works fine.
