Dealer gave me a new printout today of my built car with VIN and while going through the options, I noticed a new code that I haven't seen in previous printouts, S0C. It's right there with the other options...

8EC5X9 RS4 4.2 sedan 4dr 6sp quattro
N9N9 misano red
QH black interior
6W3 front license plate holder
996 gas guzzler
<b>S0C corporate</b> &lt;---what is this?
WSR premium package - sirius

corporate being listed on some of the first D3s back in mid '03 when there were special launch packages...I could be wrong though.
