A lot of cars dont fall down in immisions and safty features for US standards ,, so I say

I see everyday Cars that are worthless and not safe at all but its still sold around older cars mainly ,, and I red in Car and Driver that one of the American cars actruly failed the safty test and yet again its here and sold. weird huh ,,, what Motorex I think have done is improved safty in the car like Air bag tests renforced door panels.. this is all speaking out of my head ,, I wonder if the US Skyline thats sold in Motorex is ACtuly heavier then the ones in Japane if so then my idea might be true
