What do you think its worth?

So I think I'm going to try to put the S-10 up for sale in the early spring. I have a kid on the way, and also I'm sort of tired of it these days...I've sort of lost interest in it. Needs a few little things, nothing too major, for example: it needs a new air tank, the one in it has a small hole in it from rust, the speedometer gear needs to be replaced, and the engine has a small vacuum leak. My question is what does everyone think she is worth? Pics are in my profile. I was thinking of listing it for about $4,000. Maybe in a couple of years I'd be interested in doing another truck, but for now, I just want to get rid of it.

Thanks.
