You think you've seen it all.
That's when koala specialist Jane Brixter stepped in.
"She was crying a little bit, she was a little bit shaken, she was certainly in shock but I rushed her straight to the vet", Brister said.
'I had no way of knowing whether she still had her other limbs'.
Don Bigham, from Fauna Rescue of South Australia's Koala Hotline, said the female koala was relatively unharmed. "I could only see the top of her head and a paw".
There's a koala bear in there!
After several days recovery Ms Brister was able to release the koala back into the wild close to where her original journey began. The owners promised to keep an eye on her to ensure her safety.
After removing the car's wheel they realised the koala wasn't stuck, just terrified and clinging on for dear life.
Firefighters were forced to remove the car's wheel to help free the animal in Adelaide, Australia.
Ms Brister said: "It would have been hot in there".
"The koala was in reasonable condition when we extracted her from the vehicle - unfortunately though I discovered later when we took her to the vet that she would have had a joey and the joey was missing".
Ms Brister went back to the site and searched for the joey for two days but to no avail.
"We've had people think they might have hit a koala, really looked around the vehicle and not being able to find it, and then driven off somewhere but eventually hearing noises", Mr Bigham said.
But sadly that's when it became clear Kelli was missing a joey.
