The '99 Sport was a preview of the '00-'01. The suspension was stiffer than the base '97-'99 and was the basis for the base '00-'01 Cateras. The 19999 Catera Sport had contoured side skirts that flare out at the wheel wells compared to the standard flat ones. The grille was satin silver instead of chrome. Last, it had the trunk wing. The interior may or may not have satin silver trim in place of the faux wood. The wheels are 16 inch and I'm not sure if they're a Sport exclusive. Below are links to pictures.
