The amount will vary from vehicle to vehicle of course.A HUMMER H-1 will have unrecoverable vorticity destroying greenhouse flow the full length of the vehicle.
The D-B,M-B,C-111 record car probably has zero A-pillar vorticity.Ditto Renault Vesta II.Lots of factors affecting this sort of thing.
I think Hucho would have you look elsewhere for savings.
I do believe the bright metal on the Daytona helped,Hucho was involved in this kind of research at VW.I believe he addresses this drag with the Audi 100 and Golf.
