If you set the A/C to bi-level and blow some of the air conditioned air through the front floor vents the air is drawn up through the fans in the ventilated seats. This helps to send cool air through the bottom and back seat surfaces. Otherwise you are blowing warm air from the floor through the ventilated seats. Hope this helps.

I would suggest you take some of your favorite cd's, DVD-A, DTS cd's to the Lexus dealer. Play them on the standard cd player and compare with the ML DVD player. The standard cd player will not play DVD-A and DTS cd's though. These are encoded with 5.1 audio which will playback on the DVD player on the ML sound system. The sound quality of these disks (DVD-A, DTS) will blow you away - I guarantee you will purchase the ML system over the standard audio system. If you are only going to listen to regular audio cd's then the upgrade to the ML system will not be as great as stereo reproduction on both systems is very good. Hope this helps your decision.

The cost to borrow/ finance the 2008 model will definitely br higher than for the 2007 model. The lease rates will also be higher than the current rates of the 2007 models. If you can get what color and options you want in the 2007 model I would go for it now. You can bargain down the purchase price of the year end vehicles better than at the beginning of a new car season.
