Is that the only damage or is there more?
Is the roof pushed upward?
Is that rocker panel pushed in? And down?
That roof area and the metal behind the rocker panel are structural parts of the vehicle’s unibody. If those are damaged, the vehicle will never roll right again. Seeing how the rear door hinges are pushed up (meaning the B-pillar is pushed in), and looking as best I can see at the rocker panel area, I’d say the car is damaged beyond repair. The roof area will be pushed upward, the rocker panel pushed downward (both by the straightening of the B-pillar pushing them apart in a process called “splaying”) and inward.
Sorry, but from what I can ascertain from the photos the car is totaled.
The reason your sister could drive it onto the garage without a problem is because it’s front wheel drive. The drivetrain is completely contained in the front. You could actually cut the car in half behind the B-pillar, put a dolly wheel on the rear end (fixed so it doesn’t rotate) hook up a beer-barrel gas tank, cap the rear brake lines, and drive it around a parking lot. I’ve actually seen this done. But that does not mean it can ever be roadworthy again.
