A car that will meet most of your requirements is the Tata Sierra Turbo Petrol, which gets one of the longest wheelbases in the segment, translating to ample cabin space. It features a 450-liter boot (measured to the parcel tray) that is comparable for this segment class, while the 60:40 split-folding second row offers flexible luggage space.This Tata car is packed to the hilt with features, including a panoramic sunroof, dual-zone climate control, a three-screen setup, a 360-degree camera, 8-speaker JBL with surround sound and many more. The 1.5-litre Hyperion turbo petrol engine is refined with minimal turbo lag; its linear power delivery makes it much easier to drive in city traffic. It also delivers strong performance.In our preliminary testing, it clocked 0-100kph in just 10.09 seconds, making it one of the fastest mid-size SUVs available. Sierra also gets one of the best ride qualities and handling in the segment.

Considering your primary usage is in the city, a CVT gearbox is a better option than a DCT. DCTs can be jerky in stop-and-go traffic and are prone to overheating, which results in more frequent wear and tear. With that in mind, the Hyundai i20 CVT would be a better choice for you.This Hyundai car is easy to maintain and comes equipped with most of the features available in the segment. Its CVT is also one of the smoothest on the market. The i20 has a larger wheelbase (2580mm) compared to the Tata Altroz (2501mm), translating into better second-row space. The engine is refined, and the power delivery is smooth, making it an overall easier car to live with.

Since you have a Tata Safari, we assume you want the smaller car primarily for city use, and interior space or highway stability would not be that high on the priority list. Thus, we would suggest the Skoda Kylaq. Measuring under 4 meters in length, it is easy to manage in crowded cities, and the 1.0-litre engine is peppy enough. Importantly, it comes with the option of a torque convertor gearbox, which is the smoothest type to have and something you will appreciate in stop-and-go traffic. If it's a sedan, then check out the Honda Amaze. This too is under 4 meters in length, has light and easy controls, and while the automatic isn't a torque convertor. It has a CVT autobox, which is still the better option to have than an automated manual (AMT).

It is very sad that you're having to retire your well-maintained Polo due to the 15-year rule in Delhi NCR. Since you have a budget of Rs 7 lakhs, we'd advise you to get a 2020-21 Maruti Brezza or Toyota Urban Cruiser, both of which are smooth, well-built cars. Their seating position is high, visibility is good, and controls are light, which makes them very user-friendly. Also, try finding the newest possible example, which will ensure that you drive the vehicle for 9 or 10 years before it reaches the 15-year age-limit.For your outgoing car, you could consider getting in touch with used-car platforms such as Spinny; they'll do the paperwork, and should get you a good price.
