We would recommend the Kia Seltos or the Tata Sierra, as they will meet your requirements for travel comfort and features very well. With the Sierra, you should look at the turbo direct-injection petrol, as this engine is very refined and delivers good performance, too. Within your budget, you will get the Adventure Plus variant, which will be well-equipped.
In the case of the Kia Seltos, the new car has made improvements in ride quality and rear space, so this too will meet your comfort requirements. As for engine choice, we would recommend the naturally aspirated 1.5-litre engine with the CVT gearbox, as it is smooth and refined, while not outright quick. It will do the job just fine.
