you know reading your story reminds me of when i was in highschool i had a 87 montecarlo LS (rare) black with gray interior and american racing rims with firestone firehawk white letter tires loud duel exhaust it got keyed and tires slashed and they stole my valve stem caps but the thing is me and my dad repainted the car 2 3 times and it got keyed every time and it was a really nice car i started parking it in plane view were anyone could see it but it really sucked cause of the time money and labor and my pride an joy. I still have the car today and plan to take it to my highschool reunion

but in your case look into a detail shop or auto body shop they might have a fair price to fix that scratch.
