OEM Side Skirts Question, AND Comparing... 56k BEWARE Options

[ExSane]

Hey guys. I was looking into buying a set of OEM Side Skirts that came on 'some' Celicas and I was browsing around and noticed something.

How come the SS-III Side Skirts look exactly like the OEM ones? $750 for a pair.


And then I was browsing ToyotaNation trying to look for the Headlight Projectors but stumbled upon this page! Isn't #16 "Rocker Molding" the OEM Sideskirts? If so, they cost way lesser.

And then I was browsing aftermarket parts earlier and stumbled upon this page! Isn't those the OEM Sideskirts? If so it costs lesser to have that set than any of those 2 up there... maybe becuz of fiberglass? Not sure but they are all the same to me.

Now I wonder why do all these look alike and costs so much different?

You know, SS-III skirts are OEM side skirts. So #16 "Rocker Molding" part here is the same part but with different profit margin (Everything from Toyota dealer is more expensive because many reasons... all parts prices are practically "shipped" prices..., It's "real" shop with own stock place, every dealer has own % profit margin added, etc.). Now about VFiber parts. It's aftermarket company so they must be cheaper (every genuine part is expensive, you pay for brand and guaranteed quality). I don't know if that skirt from VFiber is the same like genuine OEM sideskirt, but quality must be different...
