Just to be clear i'm not advocating that people should attach tags to bodies to suddenly make money or to deceive people. I'm only saying it isn't a big deal if you are building yourself up a modified car and want some tags to put on it that suits how you want it eg a green one or a V8 one or an auto one or a bucket seat one etc. Even to make sure the rails being used matches the tags (ie replace the tags off a donor body with the originals off a damaged or rusty shell), however this only works for HQ-WB. If a person wants to be certain the original body and tags are together then that is their right, but it isn't the person who is building the car's responsibility to worry about future owners - all they have to do is make sure when they sell it or advertise it they are honest about it.
