Getting back to the original post regarding the S320CDi on Pistonheads - as suspected it is a scam - I emailed him just to check - here is the reply from the seller:
" Hello,
I am selling this car for £7,000.00 including delivery anywhere in UK.I set at a "very, very low" price to guarantee a sale. The only reason is that I need cash for a family emergency. I have to tell you that I'm currently out of town with some major problems so pick up/view isn't an option. If you want to buy this vehicle email me back with your full name and address to start the official procedure trough PistonHeads. They will send you a notification with ALL the info regarding delivery, purchase protection and refund policy so please provide your details before more questions. You will find 90% of answers in that notification from PistonHeads!
Thanks"
Why do these people do this???
