I found a LMM Duramax online that has around 200K miles. It has no mods, tunes, or deletes, and is even running the stock exhaust. The truck was a highway queen, and the service records indicate regular tranny and diff changes from around 100k miles forward. It also had the door lock and actuator warranty fixes completed.
For you guys that have or are running a LMM Duramax, do you have any regrets or suggestions re: potential problems and negotiations?
