The Fiero Store has been around for years, selling a wide variety of N.O.S. (New Old Stock) parts, and working to find marketable pieces for reproduction at a reasonable price.
I've ordered from them, probably only a dozen times in the 6 +/- years I've had my Fiero. Everything has always arrived in good shape, and I've been happy with the prices (though when some NOS parts start to get low, the price climbs REAL fast - like the wing-screws for decklid vents, the last time I saw they had them in the store, they were asking 24.95 for them! Up from the around 10 bucks a pop I paid).
So overall, I've had a good experience with them!
