I do really like this car, but I admit am baffled by a few things; the squeaky styrofoam over the spare tire, the cup holders too far forward in the console, the general lack of little storage spaces, the oddball sizes of the wipers. But I'm still trying to figure out that little odd-shaped plastic to the left of the aux jack/usb port. Does it serve any purpose or is it just a weird manufacturing defect?
