I do not believe in that too.
I will buy stuff In Kijij only if the items are in town, There were some complains on kijij about buying a cheap wii, people paid for it and never receive any items. Those seller said that they are in the US, is a legal company and said that they have an iegal adddress. At the end everything is fake....You need to understand that on Kijij suppose to be local classified not oversea shopping.
I am not sure where they are shipiing from. If the car is from the states then you need to do more work on that too - some importing issue.
No matter what I still prefer to look at the car in person. You can test drive it, check the notice of the engine. Check the tires, dent on the car etc. After that if you like it, you can ask for discount from the dealer.
BTW, it is up to you to decide if you want to take the risks or not. If you want to go ahead, please read those document carefully.
