Estimated value of a 78 Pontiac Firebird?

[EMOgoth]

I have a 78 Firebird and in general what is it worth in good, running condition.

Between 12 and 15k. I checked autotrader classic (for cars before 1981), checked some listings of firebirds from 77-79 and most were within the 10-15k range but for good running conditions it would be about 12-15.
