•2dI am from Bangalore and planning to buy a new car, preferably a diesel, as my usage will be high (around 70% highway driving). I have currently booked the Kia Seltos Diesel Manual (HTX), but I recently came to know about the Tata Sierra Diesel Manual Adventure+, which reportedly does not require DPF regeneration or AdBlue. I am confused between these two cars. Which one should I choose?

We'd recommend you to go ahead with the Kia Seltos Diesel HTX manual. The engine is smoother, more refined and efficient than Tata's. Yes, the Seltos has an AdBlue tank, and you will have to top it up occasionally. However your frequent highway usage, will ensure that the DPF remains unclogged and work efficiently.
The Sierra feels tougher, is more spacious, and has a larger boot. However Tata's reputation for aftersales service and support isn't as good as Kia's, and the Seltos also ranks higher as far as reliability goes. Hence, between the two, the Seltos is the better pick.
