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.
