When it sounds too good to be true, it is never true. Why would a foreigner buy a car and ship to him when cars in his own country could be several times lower? These kind of scams are more common for electronic items, phones, laptop, etc.. where the owners are mostly youngsters who are naive, less caution and the amount is less concerning.
Thanks for the info. Actually, i never think that, I'll lost my car! Understood that, money transferred through paypal can be revert. What I concern is, they will steal credit card info through the paypal, if I remember well, paypal need to provide credit card information for verification purposes. Or, access my paypal account to carry out other "transaction". Yes, you're right, common scams for small items like what you have mention, but just feel weird, why car ad! and this is not common at all, another reason i post here is to keep other people aware of this. however, western union is a good option.
