Pennock's Fiero Forum - Hands down the most important Fiero-related website on earth, this forum is 5,000 Fiero enthusiasts strong. It is how the Mile High Fire Club members met each other (for the most part) and it is the place to ask questions, get answers, etc etc.

The Fiero Store - I don't have anything bad to say about the Fiero Store, though I have only ordered a single item (a License Plate Holder, which was shipped to me immediately, as advertised.) If you need something that is hard to find, it might be here.

Rodney Dickman - This guy is incredible. I have never heard a bad thing about him, and he got my headlight motor parts to me inside two days. Highly recommended.

Pontiac Historical Services - A nice resource if you need more information about your Fiero. What options did it have? Is that the real color? When did it roll off the line, etc. Not a free service, but still nice.

V-8 Archie - Famous in the Fiero world for his V-8 conversions, chop tops, and several Fiero-based kit cars. Good stuff.
