Well, all I know is it is a diesel, and it is called a 'Workmaster' - but people often put the wrong stickers on these things.
So, what the heck is it? What model number? Which tranny? I know Ford had some cute names for these things, but I really only know them by number - 621, 861, 981, ... So, give us a model number. What options does it have, wide front, live pto, 5 speed, hydraulics (1, 2, ?) power adjust wheels, power steering, ?????
That price sounds pretty close for most of the 100 series Fords other than S0S tranny models, but it would help to know what you are asking about.
Others might figure out what a Workmaster is and all the options from that, but I only know the numbers. Guess I'm dumb.
Price also depends very much on where you are located, so it hard to give you an exact number. Where are you at?
