A fact box inside article (entry)?

Looking at having a car magazine, but inside the entries I would like sometimes to put in boxes with facts as you usually see in online magazines.

Example: having an article about General Motors, I wiuld inside tha rtcile, let say on the right side, put in two boxes, one with facts about GM and one with example og which cars they make.

Is that possible in WordPress? Any plugin to do that?
