Check Mileage before making a buying decision

The buying experience was not so good as the Dealer chose NOT to give Floor Mats, which as per me is the bare minimum any car dealer gives as compliments. The Dealer stated that the Mileage would improve after the first service. however, unfortunately, it worsened from 9.2 KM/Ltr to about 8 KM/Ltr. The complaint raised to Mahindra Customer Service has not been answered even after 3 months of follow-up.
