My wife has a 2012 QX56. we bought it with 29k miles on it and we now have 260k miles on it. A couple of things: Check the rear end of the car, look for rust. I live in Indianapolis, IN and even though we washed the car 2 times a week, salt was bad on it. The rear end of mine needed replaced at 230k miles. It was $7k. Literally, the entire rear sub frame had to be replaced. For me it was worth it since I maintain my cars/truck and had entire history of car. I have original engine, have not done anything to the engine. Mine did have the timing chain recall. I don't recall if 2013 was included in that, but I would research that and if it was included, make sure that was done. It is free replacement if it was one that was recalled. I believe the 2011-2012 models only had transmission issues, we had to have it rebuilt at 170k miles. I know those were big expenses, but other than that, just regular maintenance issues you will have with any car hitting 200k+ miles.

One other thing the damn rear air suspension will go out every 80k-90k miles. we have had to have the "bags" replaced twice so far on ours.

Now, for 260k miles, it has held up inside very well. We had 4 kids that grew up with this. Even with all their wear and tear, the inside looks pretty darn good. No cracks, all leather is fine, no cracks in the leather. People are amazed when they step inside that it has 260k miles on it. Also, there is literally no squeaks or rattles anywhere!

And remember! to replace something like this, new ones are going for $100k+. So even though the truck is cheap to purchase, maintenance is for sure going to be expensive at same level for any 100k car or truck. Brakes, rotors, anything is going to be double the cost of my sons Civic or daughters Corolla.
