Opinions needed on car's value

Wanted to get some opinions on my cars value, cuz i might consider selling it. It is a 1993 Purple Pearl Z28. 143xxx miles. Damn near perfect interior, ac blows cold, cruise control works, two tone cloth seats, hardtop, auto matic, couple dings on exterior (Looks good from 10 ft.) and large crack on the pass side front on the bumper cover. Only mods are full exhaust that is fully emissions legal and not loud at all. I was thinking asking 2500 so I could have a little room to work. What yall think, and let me know if Im missing anything important in my description. Thanks.

ask for $3200 and say its negotiable.

I'd ask around 3000 for it, it always helps to fully detail it out when you're selling it too. Shows that you take care of the car.
