best thing is to scroll through this section and the cosmetics section as there is always people asking these sort of questions.
some starters would be:
Lay flat rear wiper( both mecanism modifaction and changing the arm to a fiat punto arm or some thing like)
uprated head light loom
complete de badge
bee sting arial
colour coded wing mirrors
remove all un need window stickers i.e garage stickers and old alarm stickers (pet hate of mine)
aluminium gear knob
aluminium door lock pulls
hope thats a start for ya
