My 8 got hit today. I was backing out of my blind driveway when my aunt was coming up to the house. She said she say my tail lights, but didn't think to stop. Her white Ford Escort station wagon rubbed against my back bumper. It scatched off the paint in certain areas and left white lines all over it. I was able to wash most of it off, but I couldn't. She told me to tell her how much it cost and she would pay for it. I feel bad because it has to get fixed at some point since it is a lease and I don't have any money. I don't want to make her pay for it because she is 87 and she only has social security. How much do you think it will cost to repaint the bumper?
