A slightly inflated price relative to the equipment included in this car.

Comfortable, but feels a bit firmer (over small bumps) than the Q5. You can tell the car has some heft!! The electric power — 388 PS / 285 kW BEV — is incredible. The battery drops pretty quickly if you push the beast a little. The advertised 600 km range is generous on paper; expect more like 500, or even 450 in winter. The onboard technology is surprising and pushed to the extreme. After trying it, it's hard to go back to a non-electric model.

Mercedes A Class

The Mercedes A‑Class arrives as a compact charmer that dresses premium materials and a cockpit full of screens in a tidy, city-friendly package, delivering surprising agility and poise. For buyers who want a luxury badge, clever tech and a car that's equally happy in tight streets or on a spirited country run, the A‑Class offers a grown-up feel with a cheeky streak.

It's an elegant and understated car. Excellent material finishes; its two screens are very convenient for driving. Very good acceleration and braking response, great stability and good handling in corners. Good nighttime lighting, a safe, comfortable car and a pleasure to drive and travel in. My car is the A‑Class 200d. Kind regards.
