if you want to save some cash, get a hair drier\heat gun and pop that back out, It is easy to remold those bumpers, wear some leather garden gloves.. the plastic trim is fine just reattach from behind using zip ties. get some goof off and remove the brown stuff then buff out the scratches. it wont be 100% but with a little effort it would be not very noticeable. the light you will need a new lense...
ill bet that is 3k at a body shop for parts and paint
If you want to save money and avoid a deductible when going through insurance (plus it being on the car's record as a collision), you can probably tackle that job yourself!
Bumper covers are easily removed.....repair it or get a new one and have a body shop paint it for you...new lense won't be cheap, but I'd say under $1,000 for everything, as long as there isn't any structural damage underneath to the bumper structure, etc. it kinda looks ok from the indentation position.
Just be glad the sheet metal is alright...that's where the big money starts to add up!
