Hard to say just from a few pic...
While Looks nice, Many "Perfect" Fiero's are complete junk and dangerous.
Why?Many Know that even a "Perfect" Fiero Body you see Often still have Major Rust problems. More so in North US States, Canada, and more using heavy Road Salt in "Winter."
Let's say a car only drives in Summer and stored in a garage in Winter for Every Year since delivered as New... Unlikely but rare possibility.
Road Salt (and Ocean Salt if near one) is often still attacking because salt will hind in/on the car, in pavement, and more and "go active" every rain storm or even just High Humidity at any time.
Battery Tray and everything under it can "rust" from salt and/or acid when have problems w/ battery or alternator.
Other then fixing "surface rust..." DIY "Fixing" them often makes this worse. Most Body/Frame shops won't touch them because eat Hours of Time, $ and legal issues if have problems or crashes after.
Search for rust areas here then search the car for problems.
