OP here. Just elaborating more on my original thoughts. I currently have my 2018 M550 loaded with leather dash, alcantara headliner, and Bowers Wilkins audio and ACC, etc. I've been looking mainly at 2020 M850 GC's because Bower's Wilkins audio is actually available. 2021's must've had BW audio option cut along with the ECU's being unflashable. I don't see a 2021 making sense with no BW audio and paying more money for a newer car on paper, when I can get a low mileage 2020 with BW audio. Also, I'm not paying $3k+ for Femto unlock + tune overseas on a 21 when Dinan flash is like $800 for 2020's.

I've thought about a 2021 M550 as replacement for my 2018. I'd be getting the newer 523hp engine, newer front end and headlights, newer dash cluster and bigger nav screen. The rest of the car is the same and not sure I want that for another 4 years, the amount of time I generally want a different car.

I've thought about a 2023 m340 as well. It is the most modern with the newest tech and big screens, but like others have said, its too much of a material downgrade from my m550.

I've looked at 2021 Audi S6 Prestige. I feel it has the best interior out of all these options, but is also a lot cheaper. About $5-6K cheaper vs a 1yr older 2020 loaded m850. The only downfall I see is it "only" has a v6. It has the RS5 engine with electric turbo spool and is a bit down on power. With a tune, it wakes the car up to stock m850i power, which would be plenty fast. The S7 I crossed off the list because those are the same price or more vs m850i which is bonkers to me. The S6 is better appeal because its value for price.

I know all these options are 3-4 years old, but I can't think of any other newer options that are as nice and offer more or better options than these. Mercedes are all garbage and Porsche Panamera in this price range has a crap interior. I really can't think of anything else to consider.
