lol he could get a lot more for it than that.. it just needs to be cleaned up.

Clean the thing up real good.. like new.. then put it on ebay.. im sure you'll get at LEAST 200. All the things you mentioned are very minor.. just nicke and dime stuff. If the motor is running bad its no biggie, either bad tune or needs a new piston and sleeve.. that isnt enough to bring a truck's value down to 75. Does it come with the radio?

Remember, looks are everything. If it LOOKS brand new, you'll get a lot more out of it than if you put it up for sale lookin all ugly like it does now.
