This is one of the first cars in a long time to exceed our expectations. It is exceptionally well engineered and manufactured. The fuel economy is outstanding. Honda took their time and did this one right. They were obviously looking for every "tweak" they could find for economy. For a two person family with grown kids, this car is ideal. We have a Lexus RX 300 when we need to haul more than an average load of groceries or take another couple. The Insight is getting more than 2/3 of the use because of the economy and it is fun to drive and a joy to park. And this thing has zip. I have had to learn to keep my foot out of it and stay at 70 or a little below to go for the best mpg.
Economy and styling. This is an eye turner.
None that are worth the effort. This is a specialized vehicle that was designed around economy. Once you grasp that, other issues become very secondary. The special Bridgestone tires are designed to be hard to give a minimum footprint. That does make them ride a little stiff. At 50 mpg +, so what!
