I have had the RX 400h for 2 years now and my wife and I love it. The power and quick acceleration when needed was a surprise. The turning radius is extremely small and steering is the best I've ever had on any vehicle. I think the ride is exceptional and quiet. My first experience with a hybrid and it has exceeded my expectation.
Back-up camera, auto seat settings, 1 for my wife and 1 for me.
The only complaint I have with the car is that you have to be stoped before you can reset the GPS. What's up with that.
