I didn't have to go to the dealer yet...but I may now if I want my car's serial number. I also like it better having it in text form on my computer. I can save it better and "dress it up" if I want to print it out. It is strange that someone at Dodge Customer Service that readily has access to the "Build Sheet" AND the "Build Date" would not know the serial number (or maybe it is called the "Build Number"....you know computers...it only knows how to answer EXACTLY what you ask). Maybe I should reword it and ask for the "Build Number" for the SRT8 when my car had it's "Build Date" . I could probably also get them to give me the number of Inferno Red Chargers were built.
