I remember when my mom drove through the garage door when I was a kid. Then she hit the mailbox a couple times trying to get mail from car.
My father however, bought a BRAND new truck. We got stuck, went to give him a push and he gunned it... My mom and I almost face planted in the snow as he drifted his truck up on the the curb and side swiped my grandma's mailbox. It was pretty epic, and make a massive scratch all the way down the bed, until it hit the rear marker and ripped it apart. Definitely not buffing that out!
Yeah, pretty minor what your wife did. Most of that looks like it could buff out. You can repaint it as well. It appears to the plastic cover that snaps to top of bumper and touch of the lower bumper. It comes off really easily. Take it apart and you can paint it up yourself with single stage if you're feeling brave. Otherwise, a reasonable shop w/ mixing station can mix / color match w/o having to buy a whole pint of paint. Problem is the bleep'n paint got SUPER expensive. If you buy the minimum to just paint the bumper you're looking at several hundred dollars. However, a shop can mix up JUST enough and should cut you a good deal especially if you sand and prep the part yourself. Should you go that route, just get brown scratch pads from the auto paint store and really scratch it up. Then clean it with alcohol and take it to paint shop.
