The cup holders in my 06 Prius are handy for storing sunglasses, phones, etc. but I wanted to use them for actually storing a cup of coffee. So I'm thinking - wouldn't it be great to use that flat, carpeted space between the front seats? I made a little tray out of wood to fit in that space, so I can keep my ID badge and phone charger out of my pockets and out of the way. Other Prius people thought it would be handy for them too, so I had some made out of plastic (with recycled content, of course : ). Makes a great gift.
