As for Fiero appraisals I have my doubts. Right now there is a guy on eBay selling a beautifully modified 3800SC Fiero and the bids didn't go past $4,000. The owner probably has $10-$12 K in it. Its been relisted at a starting bid of $6,600 and so far no bids. I do believe that most 84-87 Fieros sell low as the demand is just not there. Only the rare 88's seems to sell for a decent price.
