Ghost300

Hi everyone, I was in a car accident the other day (nobody was injured) and the car behind me basically rammed into the rear end of my car. The plastic on the rear bumper of my 2001 RX300 is cracked and split (pretty visibly). I'm taking to the Lexus dealer on Friday, but I thought I'd ask on here for a rough estimate of repair costs beforehand. How much do you think it'll cost? Thanks!
