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.

ID.3 catches less wind. It's more pleasant, especially on the highway. Also: more economical, lighter and with the same step‑in height.

Great all rounder, surprisingly spacious cabin. Rapid and refined. Not quiet enough space in the boot for a bike, could use more ground clearance.
