Just got a 2005 sport appearance package brochure from my Potianac dealer. Looks like the hood, grills, spoiler, rocker panles, exhaust, and front and rear fascias are going to be a dealer installed option MSRP $3190. This might be good news for 2004 owners. Also, Please be advised GM is now offering a $700 allowance to NEW 2004 buyers if they purchase hood, grill inserts and spoiler with car.
