Many years ago, we noticed a similar Ford pickup parked on

the side of the road.  It was all grey primer and looked like a good running stocker..  At some point, I noticed it pass by me.  I had just finished fueling a 750 BMW.  I fired up and tried to follow the truck onto the freeway..  I openedup the BMW and at 90 mph, watched the primered truck disappear in the distance.. 

 It had the stock wire wheels, small tires and didn’t make any loud  engine noise…

We never saw the truck again…            Ever!.
