I don't mind helping, but my time is limited, so I list just a few. Also, I do not know what car niche you're interested in - car news, prices, NASCAR racing, Formula One, etc. etc.
And as profezor said before, Google it. But remember that a "car" can also be a "motor", "motorcar" or "auto" in other countries. And include words like "automotive", "vehicle", "free content" "syndicated news", etc. in your searches.
