What would you pay for this?

I'm going to be selling my 1988 Formula 350 Firebird soon. It has 125,000 miles, it's light blue with gray trim on the bottom. One rear wheelwell has rust that has eaten through (driver side), slight rust on bottom of the driver door, few spots on passenger side, the hood's paint is faded in spots, along with the roof and spoiler. None of which is noticeable from 20 feet because the rest of the car's paint shines pretty nice. 15" Five star deep rims, back one's are wider than front (silver / chrome). New ignition system (complete), exhaust has no rust on it, runs very good (0-60 mph in 5.5 sec). Brake system all new, one pad needs replacing. Interior in great condition, royal blue w/ black carpet/trim, and blue flame seat covers. CD player (not all that great but plays). No engine modifications, stock outside and in. Just wondering what ball park I should be asking for it, so what would you offer? Thanks to all who respond.

$ 1300 bucks ? see:http://www.kbb.com/kb/ki.dll/ke.kb.sp?kbb&&&usedCars;slp
