Definite, this is their MO - "I have a friend, contact him @gmail.com...", I got ripped off last year on an LOC Exhaust. They keep posting on wanted classifieds threads with 0 Posts, joining literally hours prior.
They have been all over the boards doing this. When I posted I wanted to buy an engine they sent me about 5 different “I have a 5.0” for sale emails and then sent photshopped pictures. Very much a scam
I have been also contacted by many scammers (@gmail.com) recently whenever I post WTB stuff. They always claim that they have most of the parts that you are looking for & they always try to push you to pay as soon as possible but once you pay they never reply back to you.
