Yesterday I contacted a seller about a BMW e90 M3. Now I got this answer:
First of all I want to thank you for your  interest for my car. I've almost  reached an agreement with a potential buyer. Unfortunately, it looks like there  are some problems and he doesn't have all the money to pay, for the moment. The  car is still available for sale, it is in extremely good condition,100% HPI  Clear, full service history. Currently I am on a business trip to Italy and will  have to stay here for about 6 months (this is why I am selling the car for a low  price and I am looking for a fast sale to finance the Italian project ). I left  the car in Peter's Transport custody (  www.peter-transport.co.uk  ) and they  will handle the sale for me. The V5 log book is already signed on my behalf, the  car will come with 2 keys, all service records and previous MOT's. Peter's Transport will deliver the car directly to your home address and I will  pay all delivery expenses.
  If you are interested in purchasing the car  just contact Peter's Transport  department that handles the sale directly  at: traffic@peter-transport.co.uk  and they will assist you with any questions  you might have regarding the transaction
When contacting the Peter's Transport please specify my name ( Caroline Whyley ) and the car make and model.
  Thank you

THIS IS A BIG SCAM
