We have had our 2009 NAH since June 2009.
The on-board computer for mileage runs high, as many have noted.
I just completed tallying my mileage after recording miles and gallons at each fill-up.
After 24,000 miles, I have averaged 34.74 mpg, through all seasons, right in line with EPA estimates.
With gas here at $4.20/gallon, I'm feeling fine.
Overall, it runs like any gas-powered car.
The shift from gas to electric is very mild and not an issue.
The rest of the car is quite fine: good comfort, good power, good feeling of safety.
Yes, the trunk is a bit small but that's the price for a hybrid.
And I LOVE the fact that it goes into electric at the VERY long stoplights where I live.
Bluetooth, XM radio, good feel for the road, good power, heated seats.
