I picked up the car on a Thursday, drove it halfway across the country 2 days later. This is my second Civic to own; my last one lasted 12 years and was doing great (just got to 160,000 miles and I wanted to update my car). Anyway, the 10 hour trip was actually fun. I would definitely invest in the NAV system again. My mileage is not quite what they promised, but whose is? I got 42 mpg on the highway, about the same in the city. I was getting in the upper 20s with my last Civic. Anyway, great car. The most comparable car would be the Prius, of course. I just didn't like the idea of depending on a camera to back up.
NAV feature is great and has voice command. It also has automatic climate control. The dashboard reminds me of the display on an aircraft. The real-time mpg display is fun to watch. Great sound system.
Interior colors are limited, and exterior color choices are similarly limited on the Hybrid. The front-end design is a little squatty on the 2007, but looks almost exactly like the Prius when you see them side-by-side. Other than that, no complaints!
