If it's any consolation, you can probably pop that driver side rear bumper dent out.
Take the rear bumper off, heat up some water, gently pour the water on both sides of the bumper getting the plastic all warm and malleable. Next take a hammer to it from the inside, cover the area you are hitting with a towel to ensure nothing bad happens.
I've dented by from bumper twice now and have been able to do this process to get it to hold it's shape. Obviously won't prevent cracking in the paint but at least you'll have a nice ass again.
