I just received my TEC Accessories E39 cup holder. It is a single cup holder which stores in the small storage compartment behind the ashtray. It integrates into the storage compartment and the accordian slide door still functions. Just slide the door back, press on the holder, the holder springs out, and your ready to go! Not cheap, pretty pricey, but very functional and got it for a good price. The link is: www.tecaccessories.com. Check it out.
