We had a 2004 RX 330, and one of the first things I noticed in the 2008 RX 350 is that the right arm rest is noticeably higher. They made so many little changes in 4 years, but missed some of the bigger ones. You wonder what goes through their heads.
Personally, I think the arm rest is fine just like it is and I'm neither anorexic or fat (but I am male). Nebraska99, by making a reference to 'anorexic', I'm assuming you think it's placed too close?
Yes Sir, too close and too high.
