Not all 3D models are constructed the same. Depending on the creator, some were destined ONLY for visual effects where the model consists of a series of shells -- good enough to create 3D animations. Others may have been modeled with a more faithful internal structure (chassis, B-pillars, subframe) but even then, it's possible those subcomponents are not watertight.

Most folks new to 3D printing don't get this right away. They need to.

I've been doing a lot of woodworking of late, and using sketchup to do a lot of the plans. It hurts my head to see all these non manifold drawings they use. I'm slowly shifting my thought process over to these types of drawings, but still having two faces share the same space is giving me migraines. Like a T Joint where two boards meet. A 3d printable model, that junction is hollow, but in a woodworking design drawing, that face (end of the board) exists.
