I've done about 700 miles on a new Rx400h-SL. Brilliant car. To comment on fuel consumption. I have a reasonably light foot and normally expect close to the average consumption in the spec sheet.
Driving around town with a bit of stop/start on the motorway seems to give 33mpg. Longer drive (120miles) averaged out at 35mpg. No complaints as this includes a couple of experiments to see what happened when I put my foot down.
And yes it was cold weather but I suspect there is a technique to getting the best mpg out of this machine.
Oh and in case any one else has had the proble,m motorola V500 mobiles do connect reliably by bluetooth but you have to load the address book an entry at a time which is a bit of a pain. I blame the phone!
