I have spotted 3 minor differences from my own S1. The roof conection to the windscreen, so different to mine, your interior door handles, different location and the the wheels nuts, yours are black mine are silver. All, despite the fact we both have 02 cars. I will put some images up tomorrow.
good stuff, interesting to see the pics,
I have a set of the original silver wheel hubs, the last owner bought these darker coloured ones last year I think to give the wheels a new look, I might refit the original ones in the summer, theres nothing wrong with them, jut need a clean.
I think the differences may be because mine is a little bit newer being a 2003, I know that on the S1 they tried several different hoods over the years, has yours got a wooden section where it conects to the windscreen frame?.
