Hello..... I'm new here!
I just bought an 06 LX470 this past Saturday. As a two time Landcruiser owner (2001 and 2003), I think the new LX470 is quite a bit faster than my previous LC's.
It has plenty of power for me, particularly when using the "PWR" button for passing on the open road.
I'm going to enjoy it - it was certainly worth the extra price when compared to the LC.
