Just seeking opinions on a used Duramax

I have an 03 that I bought new in 02. 132,000 and motor runs great as does the trans. Have an Edge tuner on it I run mostly in level 1 for 40-60 hp more which the one your looking at probably has stock. Friend of mine went through two Fords and is now on a Dodge since I bought mine. The mid year Fords are the ones to look out for.
Learned my lesson to check the serpentine idler pulleys a couple times a year. Do that when/if you buy It.
