I am looking for a few good websites that list private seller used car classified ads. Here are a couple sites that I like but they are mostly dealer listings and very few private sellers.

Are there other good sites with high traffic and a lot of ads? Please list your favorites.

Thanks,

I'm not too sure you will find many private listings on line. Your best bet is to get a newspaper from a large city that is close to you. You could try cars.com also, but like the other web sites they list mostly used cars from dealerships.

Pick your region.

Frequently you can find stuff in your area by checking ebay and sending a message.
