Hi Tony, yes part of what makes car modeling a difficult and advanced area of modeling is that much of the shapes are swooping around in 3D space a lot and you need to use more of the freeform surfacing toolset to construct them.

There are some links to some discussions on car modeling here:

(EDIT: looks like you've seen those before already)..
