I am looking to buy a Ford F-350 7.3L Diesel Reg. Cab long bed 4X4. It has cruise control and tilt wheel and all that other stuff except for electric windows or locks. It has 115,000 miles on it and they want $9,999 for it. Is that a good price? I just wanted to know how long these trucks will last 200,000 miles, 300,000 miles... and when I ask that, I mean how long will it be before they don't have anymore get up and go? I have no clue I have never owned a Diesel but I heard they last a long time though. So please help me and Thank you to all who answer.
