How much would my truck be worth?

i have a 1989 chevy chyenne extended bed, in a tan color. Starts up perfectly. Haven't had any problems. Has a brand nw transmission, raidiator and battery. The extrior is in very good condition. Only thing with interior is it needs a sea cover because at the top its a little ripped and neews floor mats. Also the radio doesn't work and needs the side mirrors. Also the windshield is a little crack. But all in all very great truck. Repairs i listed wouldnt cost much at all, However i am a teenage girl and its a manly country truck and i want a cute car.... What would you say its worth?? How much could i get for it? My dad is selling itfor me because he said iwont get much if they kn ow a teen is selling lol.
