Got the same message, but was from a different name & number:

SMS from # 587-773-1009: "I would luv to be the POSSIBLE buyer of ur Vehicle on AD & give u ADDITIONAL 800 to ur price.If available.EMAIL ASAP: dustinhofer40<>live.com"

Answered the email... received this reply:

"           I  was only thinking you must have had some other buyer's interested in buying it from you, So i thought the best way to outbid them is by offering an additional 800 bucks to your asking price on the add.   I'll not be able to come for the inspection my self due to present Job location but i have a Pick-Up agent who will be contacting you about when and where the pick-up will be taking place after have completed the payment transaction with you my self .

I'm actually willing to purchase it right away and be transported to Ontario where my parents reside, Please tell me a little bit more about the present mechanical condition and how often you do the service and the history  then we can take it from there.  

I will be waiting to read from you and if we can come to a quick agreement i will proceed with the payment immediately.."

Second reply from a scammer in one night. :-s
