How do you get to the officials that determine what features might be wanted? Is there a suggestion box? I could tell you this, no one in the Lexus customer service has a clue. I have a new RX350 and a IS350 and had a question that I wasn't able to locate in the manual about tire pressure and it happened to be on a weekend, so I figured I call their service. First I met with Dumb and then I figured I call back, but met with dumber. Now I did have this question on the seats of the IS-F and this rep beat them all. I'm glad I found these forums. Appreciate all you people taking the time and creating these great sites.
