yup, most of the cars are the same, the interior is different on the 300, charger/magnum are identical, the charger has competely different body panels, 300/magnum share some, more specificaly the doors, and on the 300/magnum the body lines are identical, everything mechanical is the same between all three, over in europe they sell a 300 wagon which is nothing more than a magnum with the nose of a 300 on it and 300 interior and badging.
