How many of those showed what customers could buy inside and out?
The difference between a '6' and '8' model for me is that a '6' isn't supposed to be a Halo model (it's a coupe version of a 5, like the 4 is to the 3), where as an '8' should be... Z8, i8 etc. (edit: E24 M635CSi was second fiddle to the M1, not an '8' model by name, but perhaps in principle. Original E31 M8 would have been a unicorn, even in it's own time).
Aftermarket support is defined by the number of cars on the road multiplied by the wallet size of those of those owners, if there's more owners, there's more incentive to offer aftermarket stuff, if they're wealthy the aftermarket options can be more outlandish... to me this isn't anything to do with halo-status.
Again, just my two cents but Brabus Bodo and more relevantly the Bovensiepen Zagato show that with the impending doom of the EV era, bespoke models are the way to show what you can do.
G-Class is Jim Jones for Mercedes fans, it's not a realistic benchmark for anything.
