Looking for the same info. I purchased one in April of 21 I can only find the number of CT5s built as a whole. Due to the shortages, I think this had made my car a little more special to own . From my research I could only find a handfull across the entire country and even less with the same features. Only 1 to be exact for the time doing research. Sure would like to know if I do have a “Diamond”
