I just got this used Model S, and the seatbelts are weird. They kinda twist when you buckle them, and when you unbuckle them, the buckle faces the outside of the car. Is that normal for Teslas, or do you think they're installed wrong?
It’s not necessarily a Tesla thing; it sounds like the seatbelts have been twisted. They’re easy to untwist yourself. Just try pulling them straight and see if that fixes it, here is a YT video that might help:
