Oh dear, you really need to do some reading before you list. Motors is one of only two categories that you don't have to offer Paypal, that is because there is no buyer or seller protection so if somebody pays with a stolen credit card they take the car away and then a few weeks later Paypal will reverse the payment and you will have to pay them back. You have also offered cash o delivery, that means you are agreeing to deliver the car, anywhere in Australia, and get paid when you hand the car over.

Scammers are well known for targetting inexperieced sellers and it is prettty obvious from your listing that you do not quite understand how ebay works and could fall foul of a low life and end up with no car and no money.
