Hi Peter, is that a rendering using the updated curves that I posted?

It looks different - did you create another one using 4 different networks instead of one single big network? If so then don't do that, that will also create creasing, try to build a smooth piece all as one larger section.

What did you use for rendering? The shape that I previously posted should make a nice smooth rendering.

Yup, that's why a car is a difficult model to create!

You don't have to look at them later if you make sure to draw them tangent in the first place.

But definitely you don't get a smooth result if you don't have smooth curves. If you want smooth things you have to make smooth curves to get them.

If you don't want to worry about making curves smooth with each other, than MoI (and actually any NURBS modeler) is just not the right tool for you, try using a subdivision surface modeler instead. One of the nice things about a subd modeler is that it kind of melts/blends polygons smoothly in all directions if the polygons are connected up to one another.

If you don't want to worry about things being smooth, that will be an easier type of modeling tool to use rather than a NURBS modeler.
