Mercedes G-Class

The G-Class, often called the G‑Wagen, is a blocky icon that blends unapologetic off-road prowess with a plush, modern cabin, announcing your arrival before you even step out. It’s equally at home crawling over rocks or cruising city streets, and owning one feels like adopting a very expensive, very capable personality.

I've almost had it a year and it's truly powerful on the road, very stable — the driver aids make me feel super safe. In the city it moves around very well and the fuel economy is notable. I use it both on highways and in town and it's genuinely useful.
