I got quoted around 5-8k for damage in the same area. They wanted to replace the rear quarter panel, bumper, repaint, rim, and blending.
This did not include any damage to an axle or hardtop functionality. Since I didn't have such problems arise.
Best of luck brother! Also try to receive some sort of devaluation of your car since its only 6 months old. And you can bet that this will hurt your carfax history. It is now a story car and you will definetely be hurt when it comes time to sell.
Ask me how I know.
Hope everything works out well!
