If these Ex's have unibodies like is popular these days, she's probably done. Those are designed to protect the passengers during collisions at the expense of the vehicle's integrity. Even if you can replace the visible damage, the structure of the vehicle could be out of alignment (Subarus and Cherokees, I'm looking at you) which would lead to issues with misaligned suspension and drivetrain components, uneven tire wear, unsafe driving characteristics (like differing steering response and suspension rebound) between left turns and right turns, etc.
Take the insurance money and buy another Ex.
