Given your limited running, a hybrid or an EV will not make the most financial sense. 

We’d suggest you consider a petrol-automatic. There are many options in your budget, though the Maruti Suzuki Brezza, Maruti Suzuki Fronx Turbo and Toyota Urban Cruiser Taisor Turbo are the ones that will best meet your requirements of good economy, low maintenance and reliability.

The Brezza is an upright compact SUV and has the roomiest interior of the options. Its 1.5-litre engine, however, is pleasant but unexciting.

The Fronx and Taisor are essentially the same car. Both are best with the turbo-petrol engine and automatic gearbox option. Performance is impressive, and fuel economy is also good.

Both cars offer comfortable seats and a comfortable ride, well-tuned for Indian roads and city usage, making them ideal for daily commuting. Maruti has already proven its hassle-free ownership experience to you, while Toyota is also known for reliability and smooth ownership.

Between the two, you can pick based on which design, brand and feature mix you prefer, but either will tick your key boxes of comfort, mileage and peace of mind.
 

If you like the Toyota Urban Cruiser Taisor then you should definitely go for it as it's a well-sorted car. 

The Taisor has a spacious and comfy cabin, and it comes with 6 airbags as standard. The 1.2-litre naturally aspirated petrol engine is frugal too. Toyota Taisor mileage with the manual gearbox is 21.71kpl and a higher 22.79kpl with the AMT automatic (claimed).

As you've mentioned, the Hyundai Exter is the smoother and more refined car of the two, thanks to its four-cylinder petrol engine. 

Its transmission is also relatively more seamless, and overall, Hyundai cars have a better reputation for their sales and support network too. 

Other options you could shortlist are the Maruti Fronx or Toyota Urban Cruiser Taisor 1.2 petrol AMT. 

We'd suggest getting a compact car rather than a larger one, which will help you make a judgment easily. Also, since you are likely to drive the car infrequently, it is better to pick a petrol, rather than pay a premium for a corresponding CNG version. 

We'd suggest you shortlist the new Hyundai Venue 1.2-litre petrol and the Maruti Fronx/Toyota Taisor 1.2-litre petrol. All of these are smooth and user-friendly options. 

Between them, the Venue will feel more spacious, and its high seating and SUV-like driving position will make it a touch easier to drive than the Maruti/Toyota options.

The Nissan Magnite Turbo CVT and Tata Altroz 1.2 petrol DCT, both get excellent, smooth automatic transmissions, as well as a 360-degree camera. 

Between the two, the Tata car gets our vote for its spaciousness, value, and overall robust build. The Toyota Taisor Turbo AT and Maruti Fronx Turbo AT with the 360-degree camera will be relatively pricier. 

However, these brands have a better reputation for service and maintenance.
