Does anyone know of popular sites to post classifieds?

I'm looking for something free. It's specifically for an automobile.Does anyone know of popular sites to post classifieds?
craigslist.org

Edit: beware of scammer. Written on Craigslist so read:

How to recognize a vehicle scam attempt on CL:
# Shipping a vehicle to you is suggested by seller
# eBay Motors or another intermediary is specified by seller
# Payment by Western Union or a money wire is requested
# Price is unusually low (fraction of blue book value)

If you see these tell-tale signs, flag ad as "prohibited" and avoid

Offers to ship a vehicle are virtually 100% fraudulent

eBay has no involvment in craigslist for sale ads, and any eBay or similar emails or web pages you receive are fake

Never use Western Union or wire transfer to pay for goods - only a scammer will ask for this, and any funds sent will be lost

Do not buy vehicles sight-unseen, regardless of low price. The vehicle does not exist, and any money you send will be lost.

Stories about divorcees or departing servicemen needing to sell quickly at a low price are generally fraudulent

If a deal sounds too good to be true, it probably is!
