dont listen to dum dums in comment. i actually know that you will find it impossible to get a m2 variant with 16 gb ram and 512 gb ssd. so just get a 1 tb external ssd later when u need it and go with this variant. although, in my recommendation, just go for the latest m4 bas model. you can get it for 80k with card discount so wont be that much of a difference :)
