Please follow your gut instinct on this, it sounds really bad to me and is too good to be true, as others have said why buy a car without seeing it?. I had something similar happen to me on Ebay as I was selling an antique diamond ring, I had several foreign scammers try and get me to ship the ring to them on receipt of their bank transfer and they asked me to quote for delivery etc etc - I too thought they were genuine, until they kicked off when I charged them x-amount for delivery, they then gave me horrendous negative feedback and became very abusive.
