Value Lines (55)
The simplified count is there are 55 different bodies in the Value Line (complete set shown below)
There were 3 series of Values lines. All 3 had the same 26 vehicles until the last series in which they have 3 new models making it 29. 81 vehicles total with 55 different bodies. (Thanks to Richard Cox for the help laying this all out on the Stomper Museum group)
Value Line Stompers were offered on General Mills cereal boxes.
