Logical placement of controls – it's a concept we're fond of, and are happy to report Lexus designers have built into the 2007 GS 450h. The driver's door switch panel operates the power windows, door locks, and memory seat functions; sunroof controls are located overhead; and the center touch-screen allows for quick and easy operation of the navigation system, as well as the radio and climate control systems. A little off the beaten path is a power panel that folds down from the dash above the driver's left knee with controls for the power mirrors, interior lighting, trip computer, park assist, electronic rear sunshade, and more. Some would view this as tidy, while we would prefer these often-used buttons be placed out in the open.
