These scams are easy to find - go to offerup.com or letgo.com and search for the term 'gmail'. Or simply look at the used car section and sort by the cheapest car. You'll see them post their Gmail address. Email them and let the fun begin.
Note, report the email to email@example.com (or what ever provider they use) and also to the domain registrar so it can be suspended.
Like I mentioned earlier, these guys are unique in that they arent Indian/Pakistani, but Romanian. You can hear it in their accent, and you can email them in Romanian (use Google Translate) and they will reply back.
