Used car Advice

Do you know what I should sell my chev s10 blazer tahoe edition 4x4 5 speed manual transmission for? I have searched all over the web & i'm having a hard time finding this model for sale anywhere. I was told there isn't many for sale because they are a dependable sought after vehicle. It has a freshly rebuilt engine in it. I have been driving it for 6 months & the oil is still on the full line on the dip stick. It runs & drives great. There are no dents anywhere on the body & the chrome is still shiny with no surface rust at all. Sorry if i'm asking the wrong thing to the wrong people but I don't know where to turn. I'm a single female in a small town & I have men telling me it isn't worth more than $500. I am a woman but I am not a stupid woman. I know it is worth more than $500 but I don't want to sell myself short. I like it but it's not a "girly" kinda vehicle & I want something easier to drive. Too much shifting & needs some tlc as it was parked for a long time after my husband passed away shortly after rebuilding the engine. Some advice please & thank you even if it is just some suggestions to where I may be able to find a market for my oldie but goodie s10 blazer tahoe edition 4x4
