Hyundai i30 Wagon

The Hyundai i30 Wagon is a practical family hauler that pairs roomy, sensible packaging with clean, modern lines and a surprisingly composed chassis. Comfortable, well-equipped and priced to make rivals sweat, it quietly ticks the boxes for daily life and weekend escapes while still managing a little grin on twisty roads.

As a practical user of the i30 1.5 wagon and the Skoda Scala, I can generally say the Hyundai is the better car. Why?

- Better cabin insulation
- More space for the driver, with a wider range of steering-wheel adjustment
- Interior is better made and fitted
- More comfortable driving position
- Handles better
- Stronger brakes

Cons:
- Higher fuel consumption
- Overall less modern styling
- Slightly weaker headlights vs. the Skoda

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.
