•8wI am planning to buy a new car in April/May with an on-road budget of ₹15-20 lakh. I am confused between the Mahindra 3XO AX7L, Tata Sierra Adventure Plus, and the new Kia Seltos HTX, all with automatic turbo engines. My monthly running will be 400-600 km within Mumbai city, with 4-5 occasional highway trips a year. Since Sierra and Seltos are not yet available for test drives, I am unsure which to choose. Please guide me.

Between the three cars you have shortlisted, the Tata Sierra Adventure Plus is the nicest, especially because of its turbo-petrol engine and torque converter (automatic) combination. Its powertrain will feel smooth, refined and powerful, good for city and highway driving, both.
The Kia Seltos turbo's dual-clutch automatic can feel a bit jerky at low speeds or in bumper-to-bumper traffic conditions. If your usage is mainly in the city, opt for the 1.5L petrol-IVT instead, which is a far smoother option.
Since you have the budget, and don't mind opting for a larger car, we'd rule out the Mahindra XUV 3XO as the Sierra Turbo-AT or Seltos 1.5 Petrol-IVT deliver a more premium overall experience.
