ISN'T it time they hurried up and resolved their dispute, the two feuding partners in Maruti Udyog Ltd? Check the company's sales figures for January 1998. Quite unprecedented. Sales of the Maruti 800, the best-loved Indian car of all time, the small car that changed a nation's lifestyle, dipped last month, compared to the figure for January 1997. The 800 sold 17,652 units in January 1998, down around 1,000 from last year. The Maruti Esteem too met a similar fate. January sales were 1,565 cars, compared to a target of 1,900 with heavy dealer discounts, compared to 1,629 sold last January.
