When you keep cars as long as I do, it's probably more of a shock when you step into a wonderfully, comfortable car - features have changed in 10 years. I love my new car - it's comfortable, got amenities beyond my expectations, and has good pickup. Everything seems to be very logically laid out, and easy to use. It's got a lot of room, and drives really smoothly. It will take me awhile to get used to the quietness...
I love the cooled seats (really works in this summer weather), navigation, headlights that turn as you're turning - that is really cool, and it is so comfortable.
At this time, I don't have any. I have to figure out how everything works before I determine what needs to be improved.
