The Mumbai-headquartered Telco is India's largest maker of trucks, buses and the third-largest maker of both cars and utility vehicles.

Telco said it sold 6,772 units of its Indica small car in the month compared with only 2,995 units in May, 2002. It also sold 1,983 units of the Indigo sedan and 2,160 utility vehicles. The Indigo was launched in December last year.
