From what I can remember on the ST184 WRC was that it was based on a basic SX, it came with a Spoiler, electric windows and mirros, AirCon, Sunroof (*I Think*), Mags like the GT4 and front foglights on the hatch. But can't remember anything else, oh... yeah, they were grey or a little lighter like Classique71's GT4 and white were the avalible colours...
It's similar specs I suppose to the ST204 Team Europe Edition in equipment level though the ST204 TE came in Red from memory...
