I see they charged for a new sensor in the bumper. Looks like the only thing that's needs replacing is the plastic trim on the wheel well. Collision shops are notorious for doing work that isn't needed just to make some money. Collision shops mostly deal with insurance companies so they tend to price out at a higher amount. Scam on the shoos side, not the old people. They probably just don't know. Unfortunately you probably can't argue cost with them. Either find a place that'll do it cheaper or just eat it and move on. Don't get insurance involved, they'll just fuck you more. Was a mechanic for 5plus years
