Hi Ken, yes I think that's correct, I'm not aware of any car tutorials for MoI that are geared for total beginners. Since car modeling is a pretty advanced area it's pretty normal that it's something you'd start doing after already gaining experience with MoI on other projects that were easier to do.

You can see from those links that people have done car modeling in MoI but usually not as their first initial foray into NURBS modeling.

Box modeling is probably going to be a better fit for you.
