This is my 2nd RX, previously owning a 2008 RX400h, the 450 is definitely the better of the two. It is extremely comfortable, fun to drive, well appointed & stylish. I drive a lot, so it is important that I don't feel beat up or worn out after 5-8 hours. There isn't much I don't really like about this vehicle. My disappointment has been with mpg in both vehicles. I am a "hyper-miler", squeezing every mpg out of the car I can. In the 450, after two years I was averaging 30.5 mpg; getting 32-33 mpg's on many trips. Something changed and I'm lucky to get 28.5 now. The same with the 400h after 70K. Raising the issue with Lexus netted "that's too bad", offering no interest/solution to fix it!
Comfortable seats with heaters/coolers
"Mouse" function with the console
Hybrid technology & fuel economy when it works
It is well insulated & quiet
USB connectivity & sound system
Lexus really needs to fix the hybrid/fuel economy meltdown. I was rather disturbed at the ineptness of the Lexus service department and their very strong message that there was no solution to the problem; nor were they willing to find one. Lexus Customer Services was a joke. My service representative was cocky and primarily responded to all of my concerns with "that's too bad." Not sure I will buy another Lexus after this experience!
