I would make the humble suggestions that M-B:
1.) Significantly fast-tracks convergence of ICE/Hybrid and BEV exterior design for all models. And abandon any possible reminiscence of the egg-like EQE/EQS sedan design paradigm. In it's place, clearly 2 1/2-to-3 box or "fast-roofed" silhouettes. With sculpturing as unadorned as possible, letting subtle concave and convex surfaces make the statement. Authentic "Sensual Purity" rather than glibby lipservicing. And totally devoid of tacked-on trim, inlays, juvenile, silly application of star images and functionally unnecessary vents and ducts.
2.) No compromise, highest standard of fit, finish and material quality. Inside and out.
3.) Ensure that "Mythos" is a genuine Mulliner competitior with bespoke, very limited production offerings.
4.) Cut ALL cost-consuming kitsch on more pedestrian entry level vehicles. Simply make them solidly assembled, stylistically as well as mechanically/electronically enduring and affordable for broader segments of the demographic.
5.) Make some genuinely compelling propositions to private, non-business customers with attractive leasing and rental models. And for way further down the road...offer attractive buy-back models for the purpose of attaining battery units. The recycling of these into energy storage units will be of increasing importance in the future. Especially when paired with solar panels. As will be the recycling of sheetmetals, glass, wiring, fabrics, steel, etc.
