I'm going to say scam because it is the same context in the reply as so many others. I had a scam reply on a Range Rover that was oh so similar. The ones about the guy in the US military, this one, others in the middle east or where ever. It's all bullshit.
My dream would be to play along and somehow get their account information and clean them out.
Some people are so heavenly minded that they are NO EARTHLY GOOD!
