Kijiji like craigslist, a notorious hangout for scammers. They post a car that they shut down the internet and it's advertising for an amazing price. When you contact them, they are always at some remote locations, usually military, and offer you a free car. They offer to "secure" your money through PayPal, Amazon, or any other well-known service. You will end up losing your money and there is no car. Just do not tell.
Do not buy a car that you can not see, visit, test, and talk face-to-face with the seller.
