RAC Trackstar boss Pat Gallagher said: "Car security is getting better, so it"s not surprising thieves are using different methods. This type of fraud often happens on high-value vehicles, so the financial impact is greater." Gallagher added that fraudulent transactions were more likely to happen after 5pm, when the banks have shut and the seller can"t check the draft"s authenticity.

He advised owners to do the deal in the morning, when payments can be cleared. Also, motorists can reduce the risk of being duped by asking buyers for proof of ID, verifying payment details and getting advice from their bank before handing over the vehicle.

Car crime specialist Phil Swift, from Claims Management and Adjusting in West Malling, Kent, explained drafts can be easily forged with a computer, scanner and a modern printer. "As the criminal has possession of the car, its keys and all the relevant documents, he can sell the motor on without having to change its identify," he added.
