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.

Toyota Mirai

The Toyota Mirai arrives as a bold, futuristic saloon that turns heads with sleek, almost sci‑fi styling and a cabin that feels more lounge than cockpit. It trades petrol fuss for a whisper‑quiet hydrogen setup that delivers composed, effortless progress and makes long-distance cruising a relaxed pleasure — a compelling choice if you want cutting-edge eco tech without sacrificing comfort.

Great car, I switched from a Lexus NX300h F-Sport, and in terms of comfort the Mirai wins.
