Ford F series, the best selling vehicle in America for most of the past 3 dacades... why?

For most of the past three decades, the best-selling vehicle line in America has been, strangely enough, not a family sedan or SUV but a pickup. The holder of that prestigious title is Ford's F-Series. Granted, those sales figures include not only the F-150 but also the Super Duty rigs and even commercial-use chassis cabs.

Americans love choices, something not lost on Ford's product planners whose efforts have resulted in no fewer than 75 styles of the F-150
