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.
