Had my RX 300 for a year now, and found this member site v useful. Just thought I would share the only fault with you all...
If you have trouble closing the sun roof from tilt with one press of the rocker switch - then relax, its a fault. The dealer fixed mine after I spent weeks wondering why I had to nudge-shut the roof until it closed completely without bouncing through the other side.
Apparently it just needed lubrication ...
