Coca Cola is wonderful stuff, but the lovely, curvaceous shape of the bottle is terrible in our e46 cupholders. It will rock back and forth through turns, getting in the way of my elbow when I go to shift gears. Annoying but no big deal. However, let that thing get below 30% full, don't take...

Okay, I'll throw this out and see if you have any brilliant ideas. My kids are complaining wildly there are no cupholders for the rear seats on my 2002 330i. I've been online looking for aftermarket solutions and only can find solutions for the 5-series sedans and up. Has anyone solved this...
