Trying to figure out a way to put better cup holders in my Impreza- one of them is too tiny for anything bigger than a Red Bull can, the other is really awkward. Between my coffee mug and water bottle I really would love two cup holders that hold something about the size of a 20oz soda bottle.

These things are all over eBay:

Anyone ever buy one? I can’t find a measurement on the cup holes and want to figure out if it’d work for me before I buy it.

And yes, I do know the mid 1990s Ford Taurus had a very similar device- I used one in another car I had and the cup holes aren’t big enough for what I want.
