I dont think the others are making an 8000% markup on their headers. I'd guesstimate that TA makes MAYBE $200 a set on theirs. For a $1000 set of headers, that's an okay return. About what ATR used to discount them to dealers.
I'll probably get in trouble with someone for this but screw it, I dont care. Those Ebay headers cost $90 a set from the manufacturer before you pay shipping from China and whatever taxes there are to get them in the US. Im not pulling that number out of the air, either. That is the cost.
So when you're bidding on those headers, keep in mind that they cost $90 a set and the person selling them is probably making about the same amount of profit that the person selling you $1000 set of headers is making, only with the $1000 set, you get a product made in the USA and usually something handbuilt instead of spit out on a machine in the far east.
You're also buying from a vendor that supports the Buick community and not in it to make a buck and vanish in the night when the market dries up.
And again, just to clarfiy, if the guy wants to become a vendor, he can sell whatever he wants here. I dont care where the headers come from, my only motivation is protecting the integrity of this forum when it comes to our advertisers.
