Mercedes B Class

The Mercedes B-Class is a smart, grown-up compact people carrier that dresses everyday practicality in a near‑premium polish, perfect for buyers who want comfort and a classy badge without the theatrics. It won’t set your pulse racing on a back road, but it will make school runs, commutes and grocery hauls feel pleasantly civilized — a reliable, slightly posh companion for real life.

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.

A thoroughly bad cheap car. Feels like a C3 Aircross for the poor.

That's a reason to change employers! Terrible car.

It already has a nickname, "Klapperchen"

I think any Dacia is better!

Automatic gearbox and certain features, like the windshield wipers that aren’t optional; the trunk capacity is larger on the 5-seat Frontera.

I just like the Opel better (maybe only because I'm very disappointed in VW and therefore also in its subsidiaries).

I bought the Opel Frontera GS 145PS after also testing the VW T‑Roc; so far I've driven about 5,800 km in it.

My purchase decision was based on the following criteria:
- modern design that stands out from the crowd
- low fuel consumption
- very good seats and plenty of space front and rear
- large, practical boot
- good performance characteristics
- very easy to get into
- simple controls, partly with physical buttons
- clear, well‑laid‑out cockpit

Opel has clearly skimped here. Misaligned panel gaps, no position/parking light, patchy workmanship and ill‑fitting parts — for example the partition between the passenger footwell and the engine bay — the owner's manual is inadequate and at times reads like a fairy tale; many of the functions it describes are nowhere to be found. They simply don't exist. And the claimed fuel consumption? Even with normal driving — that is, without acceleration orgies — it's unattainable.
