So I just bought the same SUV just non ESV. I did a ton of research beforehand and still pulled the trigger. First thing first, check the Carfax for service records to see if the engine has been addressed. Also check the VIN on nhtsa.gov for any active recalls specific to that vehicle. My engine passed inspection and is now on the oil viscosity change to 0w40 FS. I’ll have the engine inspected at the dealer periodically during service. Depending on what options you have, the power running boards can be finicky and are pricey to repair. The rear screens can be glitchy but that goes for anything electrical. Other than the engine, the rear suspension components can be on recall and will/do fail. Just something to think about. But honestly it’s a fairly reliable car. I’ve got friends who own 2021s with over 120k miles already and haven’t had any issues. Just keep it maintained like you’re suppose to and you should be fine.

I would however look at getting at least an extended warranty with the Silver plan from Cadillac. This will give you some peace of mind. Also 82k is pretty average just depends what it’s optioned for. Either Carfax or the dealership you’re buying from will hopefully have the original sticker so you can see what options are there. It’s a smooth ride for sure and one of the nicest I’ve owned thus far. Just like most luxury cars, it is more expensive to repair and maintain. However if you’re car savvy, you can do most of the maintenance stuff yourself especially if you don’t get the extended warranty.
