And then there are those like the Rumpler and the Boxfish that are aero but don't conform to the template very well at all.
Still, I like the template because if one uses it they won't go way wrong.

Frank,I agree with you about the limited scope of a single image.
I'm on the way to a 5-view set of drawings although this Bonneville thing has pretty much consumed all available time.
I'm also compiling a set of 'Template' comparisons to help explain some of the comments I've made about specific vehicles.
Also,I'd like to do a dedicated thread on plan-views of cars.These images are few and far between.
If everybody can hang on for awhile I'll get some stuff going.
I have six tables with me, sitting,waiting for Al to shake free and scan.
I think these will help the members with some of the Cd issues.
