Welcome Alex.
The sport has a slightly lowered suspension, alloy pedals, two-tone steering wheel, a mesh grille and rear privacy glass with sport logos. In April 2004 the sport also got a short throw gear lever.
Looking at your picture it seems you have third party front splitters and side skirts - the skirts could be TRD but the splitters look too square.
The 2004 sport came with 11 spoke alloys so again your ones look non-standard.
