I have a new in box passenger side vent cupholder for sale. It is a JDM right hand side driver part in black. Will fit any second generation RX through 2009. We had it installed in our RX400H. We thought we broke the first one we installed, but ended up fixing the mechanism after the new one shipped out.
Pretty straight forward to install using instructions found on this forum. Very useful. $90 + shipping. Originally bought it from Japanparts.com for ~$113.
