+1. Occasionally, I may have a Starbucks Frap, but that stays in the center cupholder throughout the drive and I drink it once I leave the car. I think the pores are small enough so too much liquid won't get through. BMW engineers *usually* don't overlook silly things like that. I mean usually espeically if its a more expensive model.........they forgot to light up the rear window switches and power outlet in the backseat for the X3. (you're left totally in the dark).
