From the pictures the damages do not look crazy bad, this car is def totaled in insurance aspect with the value of the car. But if you really loved the car you can always buy it back from the insurance company at a stupid cheap price. Thats if they issue a rebuildable/salvage title, but if they issue a parts only salvage title/certificate then its not worth much money in the US.

To me it looks like hardest being the quarter panel needs to be pushed out and cut and replaced. So you will need a quarter panel, trunk, rear bumper assembly, taillights, back glass. All these parts are cheap at junkyards because the majority of cars wrecked are front damaged.

You can buy the car off the insurance company if its cheap, throw it on craigslist as is and would sell quickly or you can sell it on copart. Especially if it has low miles under 100k. You might make 1-2 grand off the deal
