Re: Little Accident :( looking for advice.
Sorry to see that happen to your new Altitude, but accidents do happen and luckily damage is only confined to the bumper cover and the wheel well/finder trim piece.
I don't have experience with purchasing pre-painted bumpers from online, but I can only imagine the paint match wont be perfect....I could be wrong though! Maybe read through some of the reviews first and see what they say.
Maybe just purchase a new OEM bumper cover and have a quality shop paint it and call it a day. Swapping the rear bumper is super easy you can do it yourself in literally 15 minutes.
At allmoparparts.com I'm showing the new OEM bumper cost is $227.13, and the rear wheel fender flare is $43.84. So those costs plus shipping and a body shop to paint is what you will be looking at outside of insurance. If you want to go the insurance route that is up to you, but the problem I see with that is a shop is going to have to have your Jeep for a while, and I would be worried about them trying to paint more than just the bumper because they cant match it perfectly. So then they will try and paint up into the rear quarter panels to blend it. I would absolutely NOT want them to touch any other part of the car, and they just might.
Hope this helps.
