We've had our insight for 10 months now and have been completely satisfied with the car. We normally achieve 43-46 mpg CITY ! At 75 on an interstate it drops to 40 MPG but I usually get 50-53 on a 55 mph highway. Some routes to work net me 53 mpg city. We replaced a 4.2 litre Ford Freestar which gave 17-19 mpg city and are saving the entire car payment in cost savings. Free Car!! Ride is a little rough and firm as new cars go(typical for Honda). Interior on LX is a little too plastic. Blind spots are awful in traffic.
Love the fuel economy and the computer display. Interior is comfortable for driver if a bit firm. Nice design inside and out.
Rear view blind spots are really bad. Careful looks before lane change often result in a horn blast from one you couldn't see. Wife drives the car daily and feels she has adjusted to it. I would consider replacing side mirrors with cameras for better view and better MPG. Looking into CNG conversion for even more savings.
