I'm not really sure what to think of this:

Only Ford Vehicles Allowed in Plant Parking Lot

"Everybody's in this together. (We need) to buy the products we make and support the company."

I suppose so, but it seems just a bit strange. It's a bit like Wal-Mart employees only allowed to shop at Wal-Mart and me only ever sending my kids to Iowa State, right?
