This is not my type of car, but I must say it's great for a luxury sedan. To start off with some negative points, it lacks on acceleration and power, rear legroom can be a problem, and the steering is a little too light. What I liked about it is the electronic gizmos and its great styling inside and out. It also has a good fuel economy. And it seems like I find out about a new hidden feature everyday.
Keyless entry - just touch the door handle and you're in, power switch, gear position indicator, the light color of the speedos, the sound system, aux standard, how the lights come on when you get near the car, if it's locked (almost like it senses you).
More torque and horsepower - at least 7s 0-60, more legroom in the back, more responsive steering. Add a sequential gearbox, instead of a slow automatic.
