Yep Carsales.com.au $10 total cost until you sell it. Unlimited changes when you want and you can see the amount of traffic your ad generates. Start with the $10 ad and if you are getting lots of hits and not many enquiries, adjust the price or upgrade to the $49 ad, which aDE said is an extra $39. Quokka too is a great idea coz it's free and doesn't hurt.
