Eric, If you're accustomed to Toyota quality, you will be sorely disappointed. (Especially in first model year GM vehicles) Of all the many cars/trucks I've owned, first MY GM's have disappointed me. The worst was an '07 Escalade. Great looking in and out, great power and handling for a big rig, but a nightmare of problems. I have two '16 GX460's. Both have over 50k miles and both run, feel and look like brand new. I still have a '10 Tahoe LTZ that's been great and is used by my son.
From what I've read on this forum, the GM2kXX trucks have seemingly had an endless myriad of confounding problems. The infotainment and bells and whistles on the new GM T1 are very cool, but...
As far as the LC's go, there's a reason that the predominant safari vehicle has become an LC and an exodus from Land/Range Rovers... that's because the darn things seemingly run forever.
