>>10962013I just measured a Mcx spartan (new articulation) and its 5cm thats around 1:35 scale.
The height of these diorama garages is 13cm which means the its little over double the height of the figure.
However 1:24 figures and cars are rather big when compared to mcx figures I think, they stand at around 7,5cm which makes them more anatomically correct (look at picrel)
I think these will look a little too big, especially if you stand a figure on the stairs where I guess it will look weird as their waist wont be next to the railing, the barrel and steel pillars will prob look alright though.
If you end up getting one please post a comparison, was also thinking of getting something similar to this, but there isn't a lot of 1:35 scale diorama displays out there
