Or What. Ford has had a lot of issues with the 6.0 diesel. Premature turbo failure and head gaskets are the main issues. Next, your transmission will fail. I did a lot of research before I bought my Super Duty and decided to go with the 7.3. My truck has over 200,000 miles on it and runs strong. I just towed a truck to and from a race over the weekend with no problems at all.
If all your problems are documented and repaired through Ford, speak to an attorney about the Lemon Law (it must be repaired 4 or more times for the exact same problem to be a lemon). A buddy of mine did that with his 2005 Ford and Ford ended up giving him $20,000 back so he would go away.
