I am enrolled in an MBA program and have selected the F-150 for my economic model project. I chose the F-150, because I like mine and it is the best selling vehicle in the world. I need some help in locating montlhy or quarterly sales/production for the F-150 from 1990 to 2002. Ford send me the annual sales, but this does not provide enought data points for my project. Can anyone suggest where I might find the information?
