I've not done online transaction of car purchase online before. I need advice on it. thanks.

Cars and other things on Jiji and co are posted by individuals not Jiji themselves, so please be careful of scammers. Most if not all that demands deposit or any form of payment before you see what you want to buy are scammers. Always see what you want to buy and in the case of vehicles, always find a good mechanic to inspect the vehicle for you.

I bought my first car on jiji. I liked the car, took a mechanic and my friends to check out the car. I made adequate enquiry. At some point, the dealer was even frustrated on the way I was asking questions and trying to find out how genuine the deal was. I was ready to pay, so I was confident and not bothered about his frustration. Got the car eventually and am enjoying it. My advice is, there are real dealers on jiji. Just make adequate enquiries about the history of the car and the dealer. Also do physical checks with a mechanic before comitting your hard earned money!
