So if I'm not mistaken, you added:
- The GTI alloys wheels (jantes alu)
- The GTI steering wheel (volant)
- The GTI spoiler
- The GTI rear skirt (only one exhaust outltet though... for now?

) (bas de caisse arrière)
- The GTI front lights (feux)
- The GTI front grille (calandre avant)
- Chrome mirrors?
At first your car looked like this one right ?

Don't really know how intuitives 208 look like in the UK, but if you managed to do so many heavy modifications from such a base... wow, that is amazing and surely a shitload of work ....
Wish my 1.2 VTi would look like this ...
