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.
