Got an initial text message about a vehicle I was selling, asking if it was still available. I answered 'yes.'  Later I got another text saying the "buyer" trusted my assessment that it was in good condition and wanted the vehicle. This time it was obvious they aren't native English speakers (syntax errors). Gave no name or other information, but wanted my full name and address in order to write the "certified check." Couldn't come to see it because their work keeps them really busy, blah, blah, blah...
