I have a 92 F150 with 200,600 miles. It still runs decent with a few small issues. Doesnt use oil and doesnt smoke. It has been worked hard all its life and is in need of about $5000 worth of work (brakes, tires, suspension, engine, transmission, interior). I have a lawn service and another part time job. I was thinking of buying a "new used" truck, a 2004 F150. I know money wise it makes better sense to rebuild my old one but I am concerned about down time while doing all this. I am also thinking no matter how much I work on it its still gonna be an old truck. Is there anything that isnt serviceable or replaceable? What do you think?
