This car has been a great compromise between mileage and power. I drive 600+ miles per week, and the average 40% improvement in mileage over my previous sedan is significant, particularly considering the HAH has 10 more hp. Factor in that the HAH takes regular gas, not premium, and I am very happy with the economics of the change. I've had a few design/build quality issues, but nothing significant. If you're looking for amazing mileage, go with the Civic or Prius. If you like to get good mileage and still have considerable muscle to flex, this is a great choice.
Power, quality of interior materials, instrument panel (tech with class)
More luxury-like features-- power passenger seat, seat memory, sun roof, dimming rear view mirror; steering wheel control for XM radio that does channel to channel, not just presets.
