Yes, you're right, the Skoda Kylaq is an excellent choice that fits your needs well. Apart from being comfortable and stable out on the highway, its 1.0 TSI engine has a lot of punch, and its 6-speed AT gearbox is very smooth. Mileage is decent, too, if driven carefully, and ingress and egress are quite easy.However, you should also consider the Mahindra XUV 3XO, which has more powerful engines and an able chassis, since you like to drive. It is slightly more comfortable than the Kylaq, which can feel a bit stiff, and since you do such long distances, unlike the Kylaq, it offers a strong but efficient diesel engine option, which will reduce the running costs slightly.

Considering you keep your cars for a long time, we would suggest the recently launched Kia Seltos. We recommend the petrol variant, considering you drive below 10,000 km per year. Within your budget, you can get the top-of-the-line GTX (A) or X-Line (A) variant with the CVT automatic gearbox. The 1.5-litre naturally aspirated engine, though not the most powerful on paper, has enough poke for city driving and is well-mated to the automatic gearbox, which makes city driving easy. It also comes well-loaded with features and includes Level 2 ADAS, which is one of your requirements.If you are looking for extra performance, you can also consider the turbo petrol version, but the driving experience won’t be as smooth, and fuel efficiency will be lower. You could also consider the Hyundai Creta, which falls within your budget. However, note that the Creta is due to be replaced by early next year.

Considering you already own a Mahindra car, we would have suggested the Mahindra 3XO. It has a very smooth 6-speed torque converter automatic, but fuel efficiency from this gearbox and turbo-petrol combination is not the best.Based on your requirements and considering that you already have a large SUV and need this car purely for city commuting, we would suggest the Hyundai i20, the Sportz (O) IVT variant. It is powered by a refined 1.2-litre naturally aspirated petrol engine paired with a smooth CVT automatic.The compact size, light controls and smooth gearbox make this Hyundai car extremely easy to live with in urban conditions. The car is also spacious, feels premium on the inside, and has a large boot. Fuel efficiency will also be noticeably better compared to turbo-petrol engines.

The Tata Sierra Pure Plus petrol is powered by a 1.5-litre naturally aspirated engine that makes 108hp and 140Nm of torque. While this engine is adequate for city use and is even manageable on highway runs, for your usage in hilly regions, it will feel underpowered and struggle a bit.This will be exacerbated with a full load of passengers, and by the DCA gearbox, which is not always smooth to shift and can sap power between gears; it will be much easier to manage the performance with the manual gearbox.However, we recommend increasing your budget slightly if possible and moving to either the diesel or turbo petrol engines, as the Sierra is an excellent SUV in most other respects.
