Companys like this just increase the value of GM documented cars.Now we need some kind of kit that tests paper to tell you how old it is.I guess there is somewhere that you could send a build sheet to test it for age.The only problem would be getting a buyer to allow you to do this.Now you will need a "Documented build sheet" that comes with an age report.lol.
