If you mean body style, it's the type of car you have, then the number of doors. I.e., my four door hatch lx, is a body style LX5. If this is the number you're looking for it will be on the serial sticker for the car.
The VIN is also located on the serial sticker for the car. It is a white sticker on the vehicle frame, near the inside of driver's side door. As far as I know, the only two places on the car where the VIN is located is the one plate in the windshield, and this sticker. I know some cars have the VIN etched into their windows, and stamped on certain vehilce components like the engine and tranny, but I know escorts don't have the VIN etched on the windows, and don't think ford ever stamped any components.
