Advice on selling a car?

I have a car I need to sell in roughly a month, but it's been so long since I've sold a car so no idea what the process is like. I have a good idea of the value, and the car runs pretty good over all. It definitely has some cosmetic wear and the AC is out, but no check engine lights or anything big. Also has a rebuilt title since I bought it at a discount like that, but I've been driving it for years and no major issues. Where do I sell it these days? Are there any scams to watch out for? How do sites like Carmax work and are they worth it? I'd love to hear any and all advice.
