Believe me 1 of 6400 will never go up in value. 1 of 11 HEMI Cuda conv. now there was money in the bank. For cars 6400 is way too high of a build. Anything sold as part of a numbered series or as part of a collecter series forget it. I know tons of people saving the state quarters and each one of them think they will be worth big money in in the future. So do 6 billion other people. So just drive your car and have fun with it, but it will never make you rich.
