Good morning, I am on my 3rd RX. RX400h followed by 2 x RX450h, the last one in Feb 2013. I don't know if it's my imagination but it is a better drive than the last 450h. It also has a sport mode that is new. All in all a nice car unless you want to do some towing and then it is lacking compared to a similar sized and priced 4 x 4.
