BMW Z4

The BMW Z4 is a taut, road-hugging roadster that pairs elegant, low-slung styling with a roof you can drop on a sunny whim, delivering that pure, wind-in-your-hair driving thrill few cars manage to match. It’s an ideal weekend companion for drivers who prefer engagement over practicality — bring good shoes rather than a lot of luggage, and you’ll get a grin every time you turn the wheel.

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.
