Liz Conran said her daughter was getting ready to go out for the day when she suddenly realised the car had vanished, adding:
"My daughter went to go and let her horses out because she was going off somewhere for the day and she had to drive up there, and she got herself all ready, got to the door, and saw her car wasn't there.
"She thought that was a bit weird, of course it was still fairly dark outside, so she went round to the kitchen window and then she saw the crater and just started screaming. We just kind of took it from there really."
