The TA spoiler in the back seat is a neat twist too. If you talked your salesman/dealer into getting the TA spoiler and the guys on the line wanted to call it out on the tag, maybe they used the B80 to not confuse with the complete TA package D80. Pretty far fetched BUT what else could it mean? Whatever it was it should be on the billing history. At this point I'm ready to chip in on the PHS.
