Exactly. While the techniques for painting Warhammer miniatures may not be quite the same as painting cars (the bodyshells in particular which are for the most part just flat colour with no shading), for small details like mechanical components and the interiors the exaggerated shading method can produce come great results.
If you look at the character with the horns, on things like his helmet, the backpack, the skull and helmet on his trophy rack the shading is delibertaely made much more pronounced than it would be on a life-size model. This makes up for the lack of depth you get when you try and cast things in a much smaller scale than real-life. This would translate well to painting a car interior, or the material in a driver's fire-suit - anything that tends to have much more detail or sharper edges than you can cast in plastic at that scale.
