Grab your laptop and take with ya. Check out the aftertreatment history and make sure it's only regenning about every 100 engine hours and the dpf diff. pressure isn't much more than 3.0 and temps. in the 1000-1100 range. Check any stored codes and engine abuse history.
Look on the oil filter housing for a white paint mark(means its been updated with new orings).
Now you can grab the creeper and coveralls and check out the rest. You're in the dark about the fuel pump being updated unless the owner has documentation to prove it.
I've had 2 cm2350's and both were/are problem free and in my opinion a pretty darn good engine. Good luck and let us know how it goes ;-).
