If it was retail it would have been an XXX,that car was internal order all the way.GM still has the CD,I ordered my 04 Z06 through a little internet dealer in Louisiana at like 100.00 over invoice and had it drop shipped at my local dealer in So Ca..at that time Ca. dealers were getting sticker so that's a great program since you already are paying GM shipping plus a hundred bucks or so for the PDI and save thousands off window.
