The Maruti Suzuki Baleno or even its sister car, the Toyota Glanza, would be a good option to buy. The car is spacious with comfy seats, and it is fuel-efficient too, both the manual and the automatic version (AMT). 

In our standard test cycle, we got 13.80kpl and 17.50kpl in our city and highway cycles for the manual, whereas the automated manual transmission (AMT) achieved 11.86kpl and 17.21kpl.  

The Baleno sits below 4 meters in length and is compact enough for the city. However, if you would like something smaller, consider the Hyundai Exter. It won't be as efficient, in the manual we got 9kpl and 14kpl for city and highway runs, but this is still good. Also, you will also benefit from a slightly higher seating position and a lower price.    

The new Hyundai Venue is a good option to consider. It is an easy-to-drive SUV with good visibility, a light steering, and a buttery-smooth 5-speed manual gearbox and clutch. The 1.2-litre petrol engine is very refined and smooth, and has adequate performance for city use. 

You could also consider a Maruti Baleno or Toyota Glanza. These are very user-friendly hatchback options in that price range.

Almost all cars today are equipped with basic safety features like ESP, along with ABS with EBD. It helps prevent an accident in the first place, and these also have 6 airbags to protect the occupants in case of a collision. 

Hence, as far as safety features go, most cars have you covered. That said, if you're looking for an automatic vehicle with an excellent 5-star BNCAP crash test rating within your budget, the Maruti Dzire AMT is the one to go for. 

The engine is smooth and refined, and even the AMT (automatic) is relatively smoother than many other options at this price. The cabin is spacious and comfortable, and it drives well on the highway, too. 

Alternatively, you could consider the Maruti Baleno or Toyota Glanza, both of which are 4-star BNCAP-rated vehicles.

If your Maruti Suzuki Baleno is serving you well, you can continue with your car. If tyre pressure checks are a concern, you can buy a tyre pressure gauge. 

These are easily available and inexpensive, and allow you to check tyre pressure yourself. This will also give you time to assess if you need a 7 seater, as you mentioned, there are two growing children in your family. 

They will soon start needing their own space for comfort and safety. Waiting will help you make a more informed decision later.

We'd suggest you consider the Maruti Suzuki Baleno. Its 1.2-litrefour-cylinder petrol engine delivers pleasant performance, and fuel economy is really good. The Baleno's light controls also make it an easy vehicle to drive, which is something you will appreciate over your long commutes. 

You could get a Baleno MT Delta within your budget. But if you are open to spending a bit more, we'd urge you to get a Baleno MT Zeta that adds in more features. It includes a rear wiper, tilt and telescopic steering adjustment, and wider tyres that would make your commute safer and more comfortable.
