I have a 5.0 V8 out of a '98 Explorer that I need to sell but I have no idea how much I could get for it. It has 125K miles on it but I have the complete service history (receipts ect.) of the vehicle and all the fluids have been changed according to the service manual. No smoke, no knocks, no sticky lifters etc. Purrs like a kitten and I would consider it tip-top for the mileage it has on it. What's a good price to list it for? Thanks. ETA: I'm looking for a fair price, not necessarily top dollar.
