Launched in July 2015, Nexa today completed one year of operations. It currently has 150 outlets across 94 cities.
"Over half (51 per cent) of the customers who bought cars at Nexa were not customers of Maruti Suzuki at that point, indicating that through Nexa, we are able to attract new categories of customers," MSI Executive Director (Marketing & Sales) R S Kalsi said in a statement.
Maruti Suzuki plans to expand the number of premium outlets to 250 by March 2017 and Nexa is expected to contribute 15 per cent of MSI sales by 2020, the auto major said.
