This BASE Firebird is lacking photos and description to be asking such high dollar ($38K!)

But I this is what I got for additional details: "It has a manual top and no fold down back seat, However it is an factory A/C car. There is nothing that needs attention is turn key ready to go"
I get the impression it is Numbers matching. So let's assume that for now.

I like this bird, but wanted to know what is an accurate value. I know a lot goes into it, but let's assume it really is excellent, rust free, etc. Would it be more accurate around the $25K -$30K mark? It isn't 4sp...auto which makes it all the more common...so i hear.
Sure, I know it is all depends, but maybe a ballpark can be given by you experts. :-)

I am trying to a) see if I want to make an offer and more importantly b)start getting a feel for what is a good deal when i see it for the various configurations and engine sizes, etc.
