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.

Innovative, with generous interior space but at the expense of the boot. I have an M60 — strong acceleration and excellent self-charging, especially on the motorway.
