German luxury carmaker Mercedes-Benz on Wednesday reported its best ever sales in a fiscal in India at 13,558 units, up 20.91 per cent from the previous year. The company had posted sales of 11,213 units in 2014-15, which was the previous best, Mercedes-Benz India said in a statement. For the January to March 2016 period, the company said it posted its best ever quarterly sales at 3,622 units, as against 3,566 units in the year-ago period, up 1.6 per cent. The Q1 sales momentum achieved is significant against the backdrop of the ban on 2,000 cc above diesel engines in the key Delhi and NCR market.
