Then you get into that nutty "purist" stuff where four ("looks like original") trunk plugs are $57 in the Sunbeam Tiger world. Crazy, if you don't pull up the carpeting no one sees them anyway.   And the odd think is their other plugs are in the $2-$4 price range.  Thanks for the resource.

 Even at reasonable prices you can add up costs when you are replacing every plug in a car.  I typically look for a "close enough" plug at the self serve yards that cost next to nothing.
