Ascent 19 was rear-ended!

I got a preliminary estimate for from a Subaru approved collision repair shop. Whole bunch of things will be "removed and installed", liftgate will be repaired and spot painted and color matched, bumper will be replaced, nameplates will be replaced. Estimate is more than $5K. Needless to say it seems exorbitant and yet it is just the preliminary estimate.
To me bumper appeared fine. I was thinking it will be just slight straightening of the bottom part of liftgate.

Now I am in a dilemma: although the other party accepted fault, I am wondering if so much of 'fixing' is really worthwhile. A lot of the factory installed stuff will be removed and reinstalled. The bumper will be replaced with a repainted one, which I am sure will not be of the same quality as the original. A lot of the paint will be matched and evened out, which I presume will involved sanding and buffing, weathering the clear coat. My worry is a lot of gremlins may creep-up. Also, if the repair bill is above $750, I presume it will start showing on DMV or Carfax type record as an accident, reducing the value of the car.

If I don't get it repaired, I'll have to live with the slightly bent edge of the lift-gate, definitely hurtful esp. as it was not my fault, but so far without the other issues. Hopefully, the record for the car stays clear, although I'll lose some value due to the telltale sign of the bent edge.

Any advice or suggestions?

Our 19 was rear ended by a 20-seomthing girl in a Range Rover when we were at a stop sign in May 2021. It went to a dealer, not the one we bought it from, but a dealer who has a HUGE collision center. It was a little worse than yours and we have had no problems with it after the repair. It got a new lift gate, rear bumper and a few sensors.

That Range didn't even have a scratch though!
