Should be easy to do and look pretty good in my opinion but im not a fan of chrome parts on cars as it is tbh. take a picture from the back and try editing it white before you spend money on it.
Mmm not to computer literate Stevey last time i had a go I got it on to paint and made a right mess looked like a 2 yr old colouring in!!
I dont mind a bit of chrome its just a little to much on the rear.and I think it would match well with the rear hatch spoiler. I love the door handles as retro, if i had deeper pockets I,d like to loose the front bumper chrome wings either side of the abarth badge but as all joined and receesed into the bumper I think it would be a bit much for now.
Cheers
