I think the statistics you mentioned are blurred bcause of depreciation of the value from the cars overtime.
Why would anyone call a car advertised a year ago, or even 1 month ago?
This is quiet interesting what you say. Overhere, cars can be for sale easily up to three month. It means that the Dubai business is maybe much faster
I agree with you about the international frauds. It look's like they advertise their cars all over the world. Most can be recognized by way too cheap prices and non personal (traceable) email addresses e.g.
blablabla@yahoo.com. In a second contact they would ask you to sent half of the money in advance. They seem to have a preferrence for Western Union, Moneygramm etc.
E-mails however could be available to those who are interested but hidden to e-mail (robot) harvesters but I guess you know that already.
Last but not least, frauds can also make use of valid phone numbers. Especially mobile numbers cannot or hardly be traced overhere. Once you have them on the phone they start the Western Union nonsense that otherwise they will sent you with e-mail.
