Ok my son recently had the same car list quandary! The m2 has a juiced up n55 engine tho the 240 has the b58! The m2 is not a true M car of sorts! Still really strong money both these cars btw! You know what my son did? Bought an M4 f83 non comp convertible! Verts are cheaper than coups and both cheaper than the m3! It’s a full fat M car with the incredible S55 unit which bangs!! I believe this is the cheapest way into a modern day m car that’s still highly relevant! He got a 1 owner individual really low mileage m4 immaculate with full dealership sh, for the same money as an M240 and less than a non comp m2 in comparable condition! He’s 23 and found insurance agreeable too! F82s/F83s have bottomed out now. Shop smart
“I get that we all drive in sports mode” get this guy! Yeah maybe if you’re in a diesel but sport mode in an M car constantly is hard to live with
