Here sounds like as good a place as any.
Check the 8th letter of the VIN. I think the Grand Am is a VIN "U", where the Fiero is an "R".
Seems like I remember reading that there are some differences.
That's the Cliff's Notes version. I'm sure that someone can describe in more detail.
If you want to list it here, try "Off-Topic" or "Other Cars" sections. Either seems like it would be appropriate.
You ought to get a Fiero and don't be a stranger.
