We purchased a 2008 pre-owned certified 400H with 18,100 miles on it. It is pristine. Have driven it a week now and am getting 28.2 MPG around town and on the highway combined. Have had no problems. It is fun to drive and is very comfortable. I see some reviews stating poor mileage. Not here. If you want to drive it like a regular car, quick acceleration, high speeds, you will get the performance of a regular car. I had to learn to drive the hybrid properly and it is great. It has plenty of power, amazing actually. The only down side so far is the audio on AM stations. FM is excellent. AM sounds "tinny" though. So far, e love the car.
Navigation, hybrid MPG. Quick response and fun to drive.
