I own a 2004 Prius and now own the 2006 civic hybrid. Great car and every bit as nice as the Prius. I currently have 1,800 on the vehicle and am averaging 51 mpg on mixed highway and city driving. I don't know how people can be getting way lower than that. I do not drive like a grandma, just sensibly. Don't expect to get 50 mpg driving 85 mph on the expressway or flooring it off the light. Great car, compares very well with the Prius. If you are seriously considering hybrids, this car is a good choice. I have two kids and we can all get in with no problem. You can definitely be a hybrid only family and take trips with no problem.
Quietness, handling, looks
Make all the doors unlock on the automatic unlock feature. The driver's door only? C'mon.
