Evan it's not CSX envy. The serial number and signature obviously mean quite a bit to you, but most "non-original Cobra" owners don't place the value on that like you do. For those that do, they don't seem to feel the need to get thier panties in a wad everytime someone doesn't agree.
Do you have the same arguments with people that get a GT40 from RCR, CAV or SPF and tell them your Ford GT is real and they just have fakes.
You should read the post above from Sal over and over, but I'm sure your ego won't let you learn anything from it.
