I hope your wife is ok! First her nice patio table....and now this! Did the hit destroy the rear bumper cover? If it took enough of a lick to make the trunk lid not close, the whole tail panel is probably junked. It might be best to let it go, and just take as much money as you can get out of Allstate, and buy her another Park Avenue of that vintage. I had to go to FL for work once in 2003ish, and rented a Park Avenue. I stopped after about 150 miles and put gas in it because I thought the gas gauge was broke! Only got like 5 gallons in it! That boat got some great gas mileage. Good luck with the ordeal.
