As someone else already mentioned, did your last vehicle purchase involve you cost-analyzing every individual part of your car versus other cars in it's class? Of course not.
I know that a 33k Mazda3 and a 33k Honda Civic are "similar", but neither of them are exactly worth the same 33 thousand dollars. But who cares, really? Ultimately, even a 33k purchase is a "throw" away. You're not gonna compare control arm thickness to find the better value, and you're not gonna examine where the materials came from.
