Thoughts on purchasing a higher-mileage Duramax?

[carguy79]

Curious to ask those in the forum who have bought recent model, higher-mileage Duramax vehicles. I am exploring purchasing a year-old Denali Ultimate (with Super Cruise) that has just over 60k miles; service records show religious maintenance, oil changes, fuel filter changes, no accidents, etc. My plan is to not to use as a daily driver, but rather for occasional longer road trips and towing a camper.

Any used vehicle comes with risk, of course, so I am not expecting it to be as new. For those who have bought with higher mileage Duramax of this generation, what types of issues should I potentially plan for? Any Duramax-specific maintenance items to be aware of with higher-mileage engines based on your experience? Other things I should consider?

60K Miles is nothing on a diesel engine. I would have all the fluids changed on the vehicle as part of a prerequisite to buy. If everything else adds up and it is in good shape and a fair price, I wouldn't let that mileage stop me and all.

If only we could find a way to legally delete the smog lol

60k high mileage? lol. That diesel is barely broken in.

Any halfway decent turbodiesel that fails to exceed 300,000 miles is an indictment of its previous operators.

... service records show religious maintenance, oil changes, fuel filter changes, no accidents, etc.

If the motor oil was changed every 5000 miles, good. If more often than that, so much the better.
If you address maintenance items slightly sooner than recommended, 300,000 miles should be easy.
