Mr.
From my perspective the comparing both magazines is really not needed. Both are very good sources of chevelle info and how to do things etc. I think Chevelle World has taken time to cover more of the Regional events, Chevelle-bration along with car articules etc. and expanding the family atmosphere and National membership.
The Chevelle report covers how to do fixes repairs etc., along with some nice original magazine ad pics, dealer pics, want ads and some club coverage stuff. Some issues published have original GM Plant manufacturing pics and articules. To some degree all the Chevelle information and details published looks sort of regurgated but in a good way. I have both magazines and feel they both add value. I am like some others trying to fill in the missing issues along the way.
Good Luck
