How to 3D print a surface model?

When I have a surface model of a car (eg. the BMW M6 model of Khelifaoui Amma) and I want to 3D print it, it will cost a lot of support material. Is it possible to 'cut-off' the roof, the hood etc and make them a part and print it seperatly?

Maybe 1st of all try to write nicknames correctly (will be helpful to find model)..
If you tell about BMW M6 , than remember in what program you are working - SOLIDworks
You must sew surfaces, and make the body solid
