Maruti Suzuki's overall sales numbers are largely driven by the Maruti Tour S STD, which is a commercial vehicle mainly. As a result, there have been discussions about whether Maruti’s popularity in India’s personal vehicle segment is correctly represented by its commercial success. The question of whether the fleet operators and the taxi companies do bulk purchases, which in turn inflate Maruti’s market share and may or may not be masking individual consumer preferences, often forms the debate. Others say that separating commercial and personal vehicle sales would help provide a clear picture about which brands are popular and which are not and what people like and what they don't in the passenger car market. But others argue that commercial sales shouldn't be left out of a company's success. This typically opens up discussions about how the sales numbers of automobiles are reported and interpreted, and if the existing methods really match up to market dynamics and customer preferences.
