We have recently exposed a ring of fraudsters in the London SE5 area.
How they do it.
Fairly simple and effective, they purchase a vehicle from an out of London motor trader paying by credit card, then have the vehicle delivered to a SE5 address which is always a block of flats. Once the car has been delivered, a few days later the credit card company are informed by the card holder that, the transaction was not authorised, the money is then withdrawn from the motor trader's account 14 days later.
Of course, when the motor trader investigates the address given, it turns out that the purchaser of the vehicle is not known at this address and the vehicle purchased is no where to be seen.
How to prevent this happening to you.
Again, a simple way is to check that the purchaser is who he claims and where he claims he lives, is to check on 192.com that the address matches the purchaser's name.
A copy of the purchaser's driving license or passport can also be requested before delivery can take place.
Finally, without drawing too much attention!
The fraudsters tend to buy vehicles that, are in the region of 8 or 9 years old, from motor dealers in the north of England, for around £2,500 and in the form of standard silver hatchbacks (Toyota Corrolla's in particular).
