I suppose in some really round about extreme thinking off the wall sort of way, the owner thinks it stiffens up the frame and body therefore...????? But if "It has never been driven hard always primed", how would the driver know?
At least it does not say RARE anywhere.
Did these cars come new with a torn door strap, paint off the gauge rings and knobs missing from the radio? Description says like new condition so I assume these cars came that way.
