For those of you who don't know how to take appart a Marklin Passenger car. This is how you do it. Press the top edge of the car, where it meets the roof firmly, but carefully. there are small plastic hooks in the top of the car. When you press inward, the roof will come off. from this point on, the picture tells it all. take out the windows. Then you can do what ever you want to with the car.
