Mercedes AMG GT

The Mercedes-AMG GT is a theatrical sports car with prowling looks and an aggressive exhaust note that announces its intentions the moment it fires up. It pairs ferocious performance with surprising everyday usability — a taut yet forgiving chassis and a cockpit that feels special — making sensible buyers suddenly very good at justifying indulgence.

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.
