You could search around locally to see if someone wants to buy them or have something that will fit they will trade. A LOT of cars wheels interchange with Fiero. Sebring Conv, PT Cruiser, VW, Pont GA, Sunbird/Sunfire, Cavalier/Cobalt...just to name a few. There a list around here with like 100 different models that fit. I have great luck with things like that on local Craigslist.
