We bought our Jetta from CL and bought & sold our 4Runner on there, too. You can weed through stuff pretty quick. If there are no photos, the grammar is terrible, contact info is missing or weird then don't even bother. I set up an email with Hotmail that is only for Craigslist to prevent spam and phishing. If you email someone and it bounces or seems off, just stop replying. It's really the best way to find a used car IMHO, but being free you do have to wade through the crap that wouldn't have been in the classified.
