Any vehicle has to be reliable, but for cars like the Maruti Tour S STD that are used for high mileage, commercial use, reliability is even more important. Tour S STD is a simplified version of the Dzire and one of its most reliable options, its powertrain is less complicated and the build robust for commercial use. But this view is often contested by car fans and owners. Its stripped down nature and focus on the key components make it some argue more reliable than feature packed alternatives. But others argue that cost cutting could affect long term durability. The debate almost always gets comparisons with other budget sedans in the market, from Maruti and other manufacturers about maintenance costs, how often they get repaired, how long they stay for heavy use conditions, and so on.
