Sadly for OP, there's more to vehicle ownership and TCO than Apple Car Play and HUDs. I hope he's still convinced he made the right decision when comes time to replace oil, oil filter, spark plugs, fuel injectors, fuel filters, water pumps, timing belts, radiator coolant, AT fluid, oxygen sensors, catalytic convertors, mufflers, and much more general maintenance that doesn't come readily to mind. I hope he can take a lot of solace in his butt massage when all that's going on over the years.
I lease cars every 24-36 months depending on residual value and money factor calculations. I never get far enough to deal with fuel injectors, timing belts, etc. Will probably move back into an EV (Taycan or hopefully a nicer Model S) in 30 months.
I've driven the M5 daily for 2 straight weeks now and I truly think it's an incredible machine. It feels equivalent in terms of straight line acceleration to the P90D I owned before.
You may laugh at Apple CarPlay and the creature comforts, but don't knock it until you've tried it. CarPlay is a really nice UI compared to manufacturer stock, and even Tesla.
