My 99' had one on it when I bought it. I'm not sure what the number was. The dealer put one a new "I" on for me since it was my first Caddy. My nephew had a 86 cdv with a "XIV" on his. He sold it before I could snag the medallion!
After you purchase a new Cadillac, you recieve a business reply card, you remove the address sticker on 1/2 of it, put it on the post card and state how many Cadillacs you have owned, new or used, mail it back within 10 days and you recieve a corresponding medallion. There are no other "package" parts. I have only had gold, but I have seen pewterish black, I don't know how the color is determined.
I'm a member, but suffice to say that emblem and a couple of bucks will buy a cup of coffee. :disappoin I was sent a mailer to fill out how many caddys I have owned and was sent the medallion with the number of owned cad's on it. I agree it has been a few years since I bought my last one I believe that is the only thing I received.
