The long wait for the RX400h has been more than worth it. I have only been driving it for just a few days, but all I can say is wow, what a vehicle! The power and acceleration is incredible for an SUV with a V6. It is also very quiet (sometimes totally silent), and comfortable. I would say though that the most surprising finding to this point is that I believe (from testing so far) the EPA estimate of 31 mpg (city driving) probably can be beaten if one is careful with the accelerator. I am saying pleasant surprise since I had been hearing from message boards, etc, that it will not attain EPA estimates. Wrong! The highway mileage so far has averaged at about 27 mpg. Lexus has a new big hit.

I wish the laser cruise cruise control and smart key were available.
