I can tell you from first hand experience that the seats in these are VERY nice.
Saying BMW doesn't mean much. The X3 we had as a loaner was pretty average inside, but it isn't priced like an M car. You step up to an X5M or X6M and the interior materials, sound deadening...etc, all improve massively, but you have to pay for that.
BMW and Mercedes also make cheap cars, but people somehow see BMW/Mercedes and immediately think it's going to be a luxo-barge and are then disappointed when it isn't. These companies make a wide range of products that vary wildly in finishings depending on the price point, no different from any other brand. There's a chasm between a base Grand Cherokee Limited and the SRT for example, despite them being on the same platform, the same was the case for a 318i and an M3, and the prices reflect that.
Anyone with a DT RAM will tell you they feel pretty solid. The Wagoneer/Grand Wagoneer is based on the truck, but designed to be even more luxurious.
I often hear that tech is going to "go out of date" but I'd love for somebody to actually explain what that means. Currently, most vehicles on the market support Apple CarPlay and Android Auto, most of the recent ones can do it wirelessly and have wireless charging (like the vehicle in question). Both of these techs have been around for almost a decade. Are we speaking exclusively of infotainment systems? It's not like a HUD or digital cluster is going to go out of date, nor will heated/cooled seats and wheel, f/r parksense, cameras, climate control, auto dimming mirrors, LED headlights, air ride suspension w/auto levelling, trailer brake controller....etc. These are typically the "tech" that is included in higher trim vehicles. Some get extra stuff like night vision, adaptive cruise, lane keep and/or lane assist, self-parking...etc. I just don't see how those things get "out of date", your car isn't a gaming rig, it's not like you are going to have issues with it not being able to run the latest and greatest title in two years.
Now, this stuff can be expensive to fix out of warranty, certainly, but that's a wholly separate discussion.
