Honda Elevate Petrol V CVT

Among your three choices, the Hyundai Creta is in high demand in the used market and therefore holds its value the best. The current Kia Seltos is too new to accurately predict its resale value, but going by the resale values of the last generation, we expect it to be only slightly behind the Creta. Interestingly, the Elevate, despite Honda's good reputation, will likely see the most depreciation of the three, but in the V CVT variant you've chosen, it is also the cheapest to buy, and Honda dealers regularly offer sizeable discounts on it.

The Creta is the safest bet if you want the best value for money and strong resale value. It is good to drive, well-equipped, the engine is smooth and refined, and the IVT works seamlessly. However, do take a test drive of the Elevate as well. It offers better acceleration than the Creta, the seats are very comfortable, and the suspension feels more robust. If you can negotiate a good deal, it can represent very good value for money.

If the driving experience is the top priority, the Skoda Kushaq will be the right pick for you. It's got punchy turbo-petrol engines, and handling is very enjoyable. The updated Kushaq launches next month and packs in a few more features, and also stronger air conditioning. While Skoda has not announced prices as yet, you should get a fully-loaded 1.0 TSI with a manual gearbox within your budget. 

Of the other options, the Honda Elevate is also worth considering. Engine performance and handling are good, but refinement isn't great for this segment. 

The Mahindra XUV 7XO AX7 is great, but it might be too large for your requirements. Also, fuel economy is lower than the alternatives on your list. The Hyundai Creta is a practical pick, and the 1.5 petrol engine and manual gearbox are easygoing, but unexciting. 

If you like the Skoda Kylaq AT, go ahead. It’s a very good car to drive, feels solid, and is the most engaging of the three. Low running will naturally minimise wear and tear, and modern turbo-petrol engines are perfectly fine for city use as long as they’re maintained properly. Don’t overthink the naturally aspirated vs turbo debate purely from a reliability standpoint - upkeep matters more.
The Honda Elevate CVT and Maruti Suzuki Grand Vitara are bigger and more spacious, and both are sensible, comfortable choices. The Elevate’s naturally aspirated engine is smooth and predictable, and the Grand Vitara scores well on efficiency. However, neither feels as enjoyable or as tight to drive as the Kylaq.
Given your priorities - long-term ownership, decent safety, good NVH and low running - the Kylaq fits well if driving feel matters to you. If space and a more relaxed nature matter more, then the Elevate would be the calmer choice. But purely from the heart-and-head balance, the Kylaq is the one we would pick.

The Honda Elevate and Skoda Kushaq are good options for your usage. Given that you use a Honda Amaze, there will be a comfort factor in sticking to the Honda brand with the Elevate. 

The Elevate is a well-engineered product with a robust suspension being one of the highlights. Top versions also get camera-based ADAS, which provides an additional layer of safety, especially on highway drives. Where the Elevate will leave you a bit wanting is in the powertrain. The engine is strong and likes to rev, but doesn't have the mid-range punch of a turbo-petrol. Further, the Elevate's CVT feels basic for this class of SUV. 

The Skoda Kushaq doesn't have the same sense of space as the Elevate. However, the Kushaq has stronger turbo-petrol engines and better gearboxes. The 1-litre turbo feels punchy enough while the more powerful 1.5-litre turbo delivers exciting performance. If you enjoy driving, you'll also love the Kushaq's keen handling. The updated Kushaq that launches soon also promises enhanced AC cooling, which was an issue on the original model.

In essence, the Elevate is a safer, more familiar choice, while the Kushaq will be a more exciting choice for you. 

Of your shortlisted options, we would recommend the Honda Elevate, as it seems to meet your requirements best. It's not high on flash or features, but what it has are all the essentials, and a good set of fundamentals. It's spacious, comfortable, well-engineered, practical and quite a lot of fun to drive. 

Moreover, it is reliable and light on maintenance, so you should have a relatively hassle-free ownership experience. While it hasn't been tested for a safety rating as yet, it has all the requisite safety features. Honda cars have performed well in the past; most recently, the smaller Honda Amaze received a 5-star Bharat NCAP rating.
