"She gave her life for mine this morning" ...very poignant words, beautiful.
Dont right the car off completly, she might be saveable.
Ive seen cars in worse state than that returned to the road, though the fact the the rear glass popped out suggests a bent chassis

The best thing is that your still okay, cars can be replaced..people cant.
Maybe you could see this as an oppurtunity to overhaul the car,
Get the body straightened and into a jig, seem weld it, fill the cavitys, install a cage etc.
