I love the fact that the stereo turns off when exiting the vehicle...never had that before.
Also, my mother got in the passenger side and forgot her seat belt. Not long after the belt warning chimed. Never had that go on for a passenger forgetting to buckle-up- just for the driver.
These both may be commonplace now, but I had my last Focus for ten years. My ZX3 didn't even have intermittent wipers...I had to install that myself!
