I am the proud owner of a brand new Alfa Romeo Guilietta 1.4 170 Sportiva - this is the first time I have ever owned a new car. Sadly, I’ve noticed some small scratches where the front bumper joins the wing. I know I haven't done them and am pretty sure there not animal scratches or even vandalism.

I have asked a friend who runs their own bodyshop business and been told to return it straight away and say they've tried to cover up the imperfections.
Question is how can I prove that it wasn't anything I’ve done or anyone else for that matter and what is the likelihood of the main dealer re-spraying the front wing and bumper at their cost?
