Very poor mileage

Very poor mileage....Only 12 Kms but the company recommended 19. I am very disappointed with this car.. The salesperson Mr Sathish from Sundram Honda in Karur promised that it will give 19 Kms. But it is not true. it's a false statement. Don't say such non sense to the customer to sell a vehicle. This is not suitable to middle-class People. Don't buy this car and Don't waste your money..
