It was determined that the gas gauge worked fine, right? that would mean no one helped push her car in, she backed in into the spot herself. Where did we hear that someone helped push the 'out of gas' car anyhow?
IIRC the gas guage was tested at some point and determined to work fine but GA poured the gas that he brought to the tow yard before he tried to start the car, so I guess we'll never know if it was really out of gas.
