A Mercedes was nabbed off the drive by two thieves armed with a relay device.
The innovative duo snatched a £44,000 Merc S Class from in front of the owners home in the middle of the night.
By using a signal relay device Mindaugas Grizas, 36, and Lukas Zvirgzdys, 18, they were able to start the motor.

Doorbell footage captured one man making his way towards the house whilst the other stood by the car.
The loud engine noise alerted the owner whose motor was thankfully only missing for 12 minutes, as reported by Need To Know.
The owner of the car called the police from their home located in Breckland, west of Norwich, Norfolk.
The call was made at 2:30am on (7 Apr).
Officers for the Norfolk Constabulary stopped the car just 12 minutes later where they found the passenger still wearing a balaclava.
The device was found in the footwell alongside a GPS jammer that was still transmitting.
The duo were arrested at the scene and charged later that day with multiple offences.
Grizas from Thetford and Zvirgzdys of Hillburn Road, Wisbech were charged with stealing the car and using apparatus to interfere with wireless telegraphy.
The 36-year-old was also charged with driving without insurance and driving whilst disqualified.
The pair appeared at Norwich Magistrates Court on (8 Apr) where they both pleaded guilty.
On Monday (12 May) both men appeared in Norwich Crown Court for sentencing.
Grizas was sentenced to one year and four months imprisonment and a two year disqualification from driving.
Zvirgzdys was jailed for a year, suspended for 18 months, and ordered to carry out 200 hours of community service.
Sergeant Gary Morris, of Norfolk Police’s Breckland District Crime Unit said: “This is a timely reminder to take simple steps to keep your vehicle safe.
“The easiest thing to do if you have ‘keyless’ technology is to buy a faraday box or pouch which you can get cheaply and easily online.
“This blocks the signal from the keys meaning it can not be picked up by a relay device outside your home.”
