: I think Rob's answer above is closer to fact. Your 2002 GTi should : also have bigger brakes, different electrical harness, upgraded carpet : and trim, dashboard computer, sportier steering wheel w/leather cover, : ABS w/ASR, fog lights and, of course, the Factory sport seats w/lumbar : support.
And different gear ratio to better take advantage of the torque curve at the expense of some mileage.
