Picked up my RX 400h about 3 weeks ago and I am very pleased. Overall gas mileage is 27 mpg for the first 844 miles. My usage is about 50% highway and 50% in town driving. Lowest mileage was 25.8 and highest was 29.7. The car is extremely quiet and comfortable. Build quality is excellent and the interior design very good. It has exceeded my expectations.
Hybrid system is amazing, seamless and unnoticed when in use. Quiet, Interior quality, smooth ride.
Nav system is more complex than necessary. Would prefer just buttons for the climate controls instead of the menu choices for AC off, fan speed and vent selections. Ext design could be better.
