Tata Harrier Diesel Automatic Adventure Plus Dark Edition or new Kia Seltos Diesel Automatic GTX with ADAS? Both fall in the same price range. Which would be the better buy for long-term ownership? I may keep the car for at least 10 years, and most of my usage will be on highways. The Harrier is bigger and more powerful, but I have some concerns about Tata's overall quality, especially the electricals, service and small niggles. Which of the two would be the better choice?

Go for the Kia Seltos Diesel Automatic GTX. For a 10-year ownership plan with predominantly highway usage, the Kia Seltos is the safer long-term bet. The Tata Harrier is the more powerful and rugged SUV, and it feels more planted on the highway, but Tata still has some way to go in terms of consistency in electricals, service experience and small niggles over a decade of ownership.
The Seltos diesel is a proven package, the GTX is a well-equipped variant, and Kia’s service network and ownership experience are more consistent over the long term. The Seltos is also a very capable highway car, and the diesel engine is well suited to long-distance touring. The Harrier is the better choice if you absolutely prioritise size, road presence and ruggedness, but for a 10-year ownership plan, the Kia car mentioned above is the more sensible and dependable choice.
