Kolkata: In an unprecedented incident, Benchmark Interkrafts, a well-known dealer of premium Mercedes Benz cars, has sold a second-hand vehicle to a buyer. After a few days, some friends of the owner who saw the vehicle told him that the car appeared to be a used one. Upon subsequent inquiry, the owner found out that the dealer had earlier sold the car to Shanti Kumar Surana. It may be recalled that the same dealer had earlier duped Siddhartha Ray, who had purchased a vehicle from them. However, no action could be taken against the dealer as the car had already been sold..
