Tailgate replacement estimates on 2008 Dodge Grand Caravan

I recently got into an accident and am wondering how much it would be costing to get the trunk door/rear door/ tailgate (many names for it), I know the pricing for the new 2013 because recently my sister was in a hit and run. but I am curious about the 2008 and how much it should be around, given new/old doesnt matter.
