Not unusual for larger wagons, hatchbacks, and vans. I have had this happen many times in my Sprinter van.
My idea of "nothing much really" is way different than yours........ All up that corner of the car was probably 'propped up' almost a foot higher than the other wheels. Nothing much really......
My 99 Explorer was the same way both the rear door & rear window.Not too unusual with any car.
Jack it up to change a tire, you will see the same thing. Flex.
