I know that on my 2005 model, it came without the underdrawer seats which I retro fitted shortly after buying the car. What I have noticed is that even with the seat at it's lowest position, there's still a ton of space under the drawers. So much in fact that for a year or so, I had a CD changer under my seat, and as I'm over 6' tall, usually have the seat almost at the bottom of it's travel, and the drawer still cleared the CD changer.
