The door is designed to be easily adjustable to fit a variety of car models. You can add it to your existing auto body (an automobile exterior is not included). This subdivision poly model can be edited it at the base level (pull the edge verts) to shape the outer edge to match the shape of your car door exterior panel, turn smoothing back on and you are all set!
Works great with the car seats that we also have for sale at an equally great price (see asset link on the right).
