You should choose between the Maruti Suzuki Ignis Zeta AMT and the Maruti Suzuki Wagon R 1.2 AMT ZXI Plus. Both models are powered by 1.2-litre petrol engines that give them a power advantage over other automatic Marutis in your budget (namely, Celerio, Alto K10 and S-Presso).

Both use automated manual transmission or AMT-type automatics. While these aren't the slickest automatic gearboxes, Maruti's AMTs work smoothly enough if you adopt an easygoing driving style. Fuel economy is also excellent.  

Of the two, the Wagon R is more spacious and has a more absorbent ride comfort. On the other hand, the Ignis packs in more features for the same money. If cabin space isn't a deal breaker, opt for the Ignis. 

You can go for CNG if the network in your city is good, and the car that you can pick is the Maruti Suzuki Wagon R. It comes with 6 airbags, taking care of your safety requirements. Also, it comes with an antilock braking system and electronic brake distribution. 

Moreover, it gives great fuel efficiency with CNG, and you have the benefit of switching to petrol when you want. The other option is the Maruti Suzuki Celerio, again a reliable car with good features. 

The Maruti Suzuki Wagon R will suit your requirements of an automatic car that's easy to get in and out of and below Rs 7 lakh. The car is also easy to drive with light controls. It is, however, a bit old now, and if you would like something newer and more exciting, you could look at the newly launched Tata Punch. The car's taller height allows for easy entry and egress, along with doors that open to a full 90 degrees. It will require you to stretch your Rs 7 lakh budget, though.  

The Maruti Suzuki Wagon R is the right pick for your requirements. Its high seating makes getting in and out very easy. The large glasshouse also gives a great view of your surroundings, so you won't need to crane your neck for a better look. 

The Wagon R is also easy to drive, though we'd recommend the 1.2-litre petrol version for its added power. The standard 1.0-litre petrol feels dull, especially on inclines.  

Buying a BS4 car in Delhi NCR is not a good idea, as you run the risk of being unable to use it when the AQI worsens and GRAP measures are implemented. This can disrupt your commutes and cause significant inconvenience. If you want to buy a used car, we suggest looking for a BS6 option or a vehicle that is no more than 5 years old.

A Maruti-Suzuki Wagon R would be the ideal new car for you.  Its high seating position offers the double benefit of making learning to drive easier for beginners and making it easier for elderly people to get in and out. Wagon R prices range from Rs. 6-8 lakh, depending on the variant. 

For your usage, the Maruti Suzuki Wagon R can be an excellent choice. It is one of the most spacious budget cars, and its reliability is well documented. 

Maruti has the most expansive service network; you won't find it difficult to find service stations, which can be an issue for other brands, as your parents live in a remote location. 

The variant we recommend is the Wagon R VXi Manual with the 1.0-litre engine. The 1.2-litre engine is worth considering only if you frequently drive in hilly areas, as it makes uphill driving a bit more effortless.
