Although it’s the 3rd video in the series, Cars 3 is kinda awesome. If you want to watch it online then here are a few options (we checked these as recently as November 2018):
- Amazon Video – The entire film is available on Amazon Video, and you can sign up for Amazon Prime completely free in 10 seconds and have access to it immediately (Amazon Prime users get Amazon Video access too), plus a whole bunch of bonus content.
Just cancel before the 30 days is up and you don’t pay a penny, simple. If you’re wanting to watch Cars 3 for free and in high quality right now, then a free trial with Amazon Video is your best option.
