Great comfort for long drives, the noise is very low even at high speed, high and smooth acceleration, excellent stability, remarkable reliability, very robust mechanics suitable for bad roads, a wonderful car. Net superior to BMW 5 series and Mercedes E class in all aspects. "Zero" maintenance costs. The fuel economy is not that big for a sporty driving style.
The VDIM system makes a great difference between this car and any other. The snow mode for traction control is over my expectations, the car having a great stability on icy roads. The Mark Levinson audio system is outstanding.
Headrest to be adjustable back and forth, bigger fuel tank and trunk. A USB port would be useful, too.
