Two robbers who posed as car buyers left a man with a broken leg before fleeing in his vehicle.
Police said two men travelled to a property in Fern Mead, Cranleigh, to view a car which had been advertised for sale online.
The owner was attacked as he showed the pair around the 2011 model black BMW X5 on Tuesday evening (June 12).
Officers said he was left with a broken leg, bruising and swelling. The attackers then fled the scene in the 4x4.
