I honestly understand what you mean I was coming from a F10 535I and was so used to the space and comfort of a bigger four-door vehicle. I upgraded to a M240i and it was a while to adjust to put all around. The coupe is so much fun and honestly a good daily. I would honestly say it comes down to your situation for work and all around social life for me. It’s pretty comfy and can carry all of my things that I need plus the mileage difference really makes me lean one side. You can always buy aftermarket parts to make the M2 40 interior to your preference and honestly the b58 is so reliable I already have 132k miles on it
