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.

The Mazda is a more elegant car, less cumbersome and, even though it’s also an SUV, it feels less like an SUV and more like a regular car. Besides having an interior that feels more "like a real car" and less "smartphone," the finishes are also superior and the dynamic behavior is better. The lower power is made up for by being about 100 kg lighter, a lower vehicle height (more aerodynamic efficiency), and a smoother drive thanks to a high-displacement, non-turbo engine. The equipment is very similar but the Mazda just has more "class." Prices are comparable with equal equipment, and the difference is size: the Tucson being 11 cm longer is noticeable, especially in the boot — the Mazda’s is fine, but the Tucson’s is cavernous. If you don’t actually need something that big, I recommend the Mazda.

Nice luxury car, although I'm not sure I find the oversized rims that attractive. On the other hand, I like the Mazda 3 better.
