it depends what you call the factory weight
The "magazine" listed curb weight includes no passengers, but a full tank of gas.
The "gross vehicle weight" on the sticker by your door includes a passenger (175 lbs) for every seat with a seat belt that came with your car. So subtract 175*4 = 700 lbs from the "gvw" to get the curb weight, which as before includes a full tank of gas.
