Yeah.... I'd like to hear their argument about how a body style that they haven't made for over 40 years is going to be harmful to them by someone else making the replicas. The only way they COULD support that argument is IF they are intending to reintroduce that body style in the future. Heck, even patents expire in 17 years.
The judge should just throw the case out of court and the defendants file a countersuit claiming abuse of process and defamation of character. I guess libel could be on the table as well, since falsely claiming someone has violated the law is one of the few clearcut ways to win a libel lawsuit.
