Buying advice for a 2017 Denali - what to look for?

[2015LTZ]

Hi all, i am looking to buy a 2017 Yukon Denali. It has around 60,000 miles. Still with the first owner. I will do a test drive tomorrow.
What are the known issues with it? I understand it has the 8L90 which is prone to issues?

What should I be looking for and what immediate things are to be done if I go for it.

I am based in Saudi. The car is a middle east spec car.

Service records would be first. Assuming it has the 6.2L engine listen for a ticking sound. Unfortunately this engine has had its share of lifter problems with AFM. However since it’s a Saudi truck maybe it doesn’t have it? Not sure. Also check the AC these have had condenser failure issues. If you have a trusted mechanic have it checked out. If you buy it get all fluids changed.
