Brand New Edelbrock performance intake's go for $400.
Used ones should be no more than $100, there is never any way to verify a used part's condition unless you get it checked out by MPI tests. There can always be microscopic cracks in the metal which will shorten its useful life.
It does not matter if you are selling one used that has only seen 500 miles, it should still be worth no more than $100, used parts are ripoff's anyways, get a new Edelbrock Performance Intake and Throttle Body, get some Fel-Pro Gaskets for it and you can gain 60 HP cumulatively just by bolting those on.
