I posted an advert on Kijiji selling my car.  I live in Toronto, Canada.  I got a sms from a woman in the USA.  Funny thing is that within 4 minutes I had the same type of sms from a guy who also lives in the USA.  Why would 2 different americans want to buy my 8years old car? I googled the sms from the guy is a listed scam.  I did not reply to the woman.  
I believe it must be the same scam, they want your paypal email address.

I too just received a strange text from this number asking me to email him directly if my car posted on Kijiji was still for sale.  Seems like a scam I did not reply.

Have a new phone and haven't really given out the number, but just got a "Hey" message
