The tv can be placed on the roof of your car, laid on its back and strapped down with ratchet straps. This is how i got mine home on a 2020 BMW 330i.
1. Carefully set it with the help of a store associate on some sort of protective cloth. (Protect the car's finish)
2. Open all doors, so that the straps (2) can be run through the car's interior, ratchet till snug. (DO NOT OVERTIGHTEN)
3. Close doors with loose strap ends inside car and not dangling outside.
4. Pay attention to driving! The tv will be fine. Don't allow it to distract you.
My home was 12 miles from the store, and i drove 50mph without incident.
