I own a Tata Altroz DCA Petrol and have been driving it for almost one year. It has completed 30,000 km. I want to upgrade to a diesel automatic and have shortlisted the Sierra and Curvv. I need your help for choosing the best one and even suggestions about other models.
Given your usage of 30,000 km in a year, a diesel automatic is the right move, and both the Tata Sierra and Tata Curvv are strong options. The Sierra is the better choice if you priorities space, comfort and a more premium cabin experience. It offers a larger, more comfortable rear seat, a more spacious boot and a more relaxed long-distance touring character. There's also a lot of new features and tech with the Sierra, though on the higher trims. The Curvv, appeals with its coupe like styling but the trade-off is that it is not as spacious or as comfortable for rear-seat passengers. Between the two, the Sierra is also likely to hold on to its resale value better and it is the one we would lean towards.
