I recently obtained a "clean vehicle" sticker in California that allows the use of carpool lanes with only one person in the car. It just doesn't seem fair to get great mileage while cruising past stopped traffic on the freeway. It is normal to get at least 500 miles per tank, so you don't need to fill it up very often, and it doesn't cost very much at that. Compared to what I was driving before, the savings in fuel costs alone is enough to cover payments. It is amazing that it performs the way it does with only a 1000cc engine, which is smaller than many motorcycles.
This car is extremely well built, solid and reliable. The all-aluminum frame and outer skin is strong but very lightweight, providing a unique driving experience. High responsiveness and very agile. Outperforms in winding mountain roads. The car has almost all the features of a luxury vehicle.
Cruise control is needed. It would be nice to have a super-economy mode in addition to the two performance controls, drive and second (wider cvt rpm range). The auto-stop feature is great, except that it would be good to have a manual auto stop button for start and go traffic.
