I put around $6,000 in mine over the course of 10 years. New Expeditions start at $50K. I like the truck and love not having a car payment. Any used vehicle will need repairs sooner or later. Why do you think people get rid of them? You did the repairs, now drive it a while. Why let a buyer benefit, from your work. Find a friendly, fair mechanic(they are hard to find) and learn how to DIY repairs. The 1st Gen Expeditions only weakness is rust. Other than that, they are long lasting, high mileage vehicles.
