5 months young and Macke in the door

Hello, with today an ignorant foreign property (Arschl… I don’t write now) in the parking garage with its door a thick Macke cut into the new car. Estimated 4 X 2 mm Macke…except for the primer Did my vehicle park extra to a few cm on the wall that the parking space next to it is still large enough….the Macke is exactly on the fold that runs over the door at the Mercedes W204. What’s your advice? – Spot / Smart – repair ? – try it yourself with paint pen? – just leave it like that = it looks away…and doesn’t rust either? Let the door repaint……excludes probably. Am totally pissed…. Thank you….for your recommendations. veyron
