•3dHi, I need your advice. I drive around 1,000-1,500 km per month in Brahmavar/Mangalore, with 70% city use and 30% highway driving. We are a family of three, and I also travel with a large dog in the boot area. I plan to keep the car for 5-7 years. My budget is Rs. 15-20 lakh. I currently own a 2018 Maruti Suzuki Swift Dzire Petrol ZXI. I am considering the Tata Sierra AT, Harrier AT, and Kia Seltos AT. I have a few questions: -Which one would be the cheapest to run per km over 5-7 years, considering fuel, service, insurance, and resale value? -Would petrol or diesel be better for my usage? -Which one is the most reliable and easiest to live with for city driving, carrying a dog, and luggage? -Are there any concerns with the Sierra being a completely new model?

With 70% city use in Brahmavar/Mangalore, 1,000-1,500 km a month, and a family of three plus a large dog, the Kia Seltos diesel automatic fits best. Diesel makes sense for your running. Your 30% highway mix each month helps keep the DPF system healthy, so city use should not be a worry. If most daily trips are very short stop-start runs, petrol is simpler, but your usage suits diesel better.
For reliability and ease in the city, the Seltos is the most proven and the easiest to steer and park. The trade-off is space: the boot will take a big dog, but dog plus large suitcases may be tight. If you often carry the dog and lots of bags together, the Tata Harrier diesel automatic is roomier, but it will cost more to run.
Overall, the Seltos diesel is a good fit.
