Scratches by garage wall

Good morning, I took over my grandfather’s car in the autumn of 2017. When he parked out, he briefly striped the garage wall and a longer (but not deeper) scratch on the passenger side, you can see the result in the photos. Now I want to sell the car. Does it make sense to go there again, if so, by what means and above all how? Or rather advertise with the scratches and don’t do it anymore?
