This is the shocking moment thieves stole a Mercedes from a driveway in the dead of night, just hours after the car was viewed during the day.
Doorbell footage shows a man wearing a baseball cap and a dark-coloured hooded jacket talking to the luxury car's owners on March 25 at about 7.05pm.
He is being shown around the white Mercedes by two females, as a man stands behind with his arms crossed, which is parked up on the paved driveway in Watford with its doors and bonnet open.
The supposed perspective buyer waves his arms around before peering into the front passenger side and then appears to ask how many sets of keys there are.
