re: Best criteria for used tahoes. And is a new Tahoe pretty good?

My lifters on one cylinder just went out just over the ridiculously low 60k powertrane warranty. 21 Tahoe. On the interstate as well. Tried to get replacement engine and none were available. Trying to get lifters replaced and drive the damn thing to the nearest dealer for something else. Absolutely ridiculous that gm can’t build something that last over 60k miles. Better than my buddies whose lifter went out under 10k.
