Inspired by the Toyota Sienna's seat-mounted cup-holders, I have long-sought a location to mount a flip-down beverage holster. Sure, you can screw through the carpet, but doesn't that look a bit tacky? Into the dash? NO! The stereo bezel? Only if you want it to fail horribly on you.
And then it hit me: Why do my (virtually nonexistent) rear passengers need an ashtray? I've only had one person smoke in my backseat in college, and she was not a pleasant person. So I removed the old ashtray holster and bezel and installed this $6 cup holder from Amazon: http://www.amazon.com/dp/B000Q86IQQ/ref ... hrb1NKESRD
BEHOLD:



Aluminum screw backing plate because I am paraniod that I'll spill on my fancy new carpet.

The way it sits on the transmission hump supports heavier drinks.

I'm still on the lookout for Siennas in junkyards to steal their cup holders. (Toyota wants something like $40 for them new.) For now, this is perfect. I even cut up a PBR coaster and fit it inside the lid because I am such a hipster.
