The 2005 Buick Park Avenue changed to a vertical bar grill that has an oblong oval shape. The 1997-2004 Buick Park Avenue grille has a more rectangular look than the 2005 model. The grill still has vertical bars, but it is not as oval shaped as its predecessors. May only be available from the dealer at this time! $$$$$
