OK folks, what's fair market value nowadays?

I've run through all the bluebook websites with widely varying results, and I've seen listing between $4500 - $8000 (highly modified) for mid to high hundred thousand mile 94-95 Cobras. For those of you that have purchased/sold them in the Northeast, what seems to be fair market value for these Cobras? As badly as I want one, I'm not going to spend $7000 on a 94 Cobra when I can get a 95 GT for $3500 with less than 100k mi (have seen that a few times around here) and make it just as quick if not quicker. Although, I suppose I'd lose and Cobra specific features such as handling modifications.

I live in Chambersburg (Franklin County).

I wanted to get a Cobra because of the GT40 heads and I'm a college student (I'm 20). I also thought they had bigger brakes, but maybe not? I figured in the case that I won't be able to build it up a bit before I get out of college, it would already be plenty powerful to have fun with. I imagine the GTs are pretty fun to drive stock, but I want to have a car that breaks the tires loose relatively easy with like $500 in mods (gears obviously will help that). I've been looking at the GTs, but most around here are either fully modified (supercharger & all supporting mods), or they're beat as hell. I'll just keep my eyes open a little longer to see what comes across.

I have a guy down around Balitmore that claims to have a freshly painted red 94 cobra for $4500, but I can't get him to call me for the life of me, something always comes up. Freakin craigslist lol.
