If you have a flat tire and take out the small spare wheel, inflate it and mount it, you can drive away. But what do you do with the flat? It doesn't fit in the trunk. You either leave it behind or you leave your passenger behind, the wheel can only be transported in the passenger seat. Anyone have a better idea?

LOL, that is an awesome question. Tie it to the trunk lid?

I am amazed that MB did not thing about this issue when they designed the car. I guess they just assumed that no one would try and change there own tire. I would carry a can of fix-a-flat with you so then you don't have to worry about it.
