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.

Aston Martin DBX

With the DBX, Aston Martin has wrapped its trademark sports-car drama into a high-riding package that looks like it could sprint off the driveway and into a gala, while the cabin pampers occupants with handcrafted leather and theatrical attention to detail. Behind the wheel it feels like a grand tourer that learned how to tackle country roads, serving up surprising agility for such a stately presence and keeping rivals honest with its rarefied blend of performance and luxury.
