What the paint is meant to look like
I know which one I want my car to look like.....
Is this a one off story? Sadly no. I get people seeing me all the time asking why my cars always look so good. They say they 'keep them spotless', but just look so dull. It's not hard at all to keep your car looking the best. Obsessive? Can be for some, but just about everyone wants a nice looking car, and a new car to look new for a long time.
And yes, to fix this damage is expensive. Sure you could claim insurance, pay your ~$500 excess, and then higher premiums from then on, just to fix damage that is easily avoided.... That's if your insurance will accept your claim at all....
