Those numbers have had a good margin above the actual top speed for so many decades now that it hardly counts as advertising any more, it's just a fact of life. (I think I was eleven or twelve last time I looked in through the window of a car and went "Wow, look, it does 220! [km/h]" because that was the top number on the speedo. Must have been 1975, -6.)

Whatcha gonna do if it does less, demand restitution from Ford with a claim of "false advertising"?
