We just returned from a 4100 plus mile road trip and I have to say the Insight was nice to ride in. Comfort level and space was fine and the mileage was fantastic! It saved us a ton of money in the end since we traded in our Honda Element. We averaged 47.8 MPG's. Very satisfied. I used Fuelly to track the trip and the HUD gauge was only off by about 1.25 mpg's per fill up. As usual, 91-93 Premium gas fill ups resulted in 4-5 more miles per gallon. Worth it.
