Maruti Suzuki S-Presso Std (O) MT

Unfortunately, given your tight budget of Rs 6 lakh, you don't have too many options. Choose between the Maruti Alto and the Maruti S-Presso, both of which come with the same 1-litre petrol engine mated to a 5-speed AMT automatic gearbox. Both are also fairly similar in terms of fuel efficiency, with the Alto returning a claimed 24.90kpl while the S-presso is said to do a marginally higher 25.3kpl. 

Maruti Alto AT prices range between Rs 5.53 lakh to Rs 6.07 lakh (on-road Delhi), while S-presso automatic prices range between Rs 5.31 lakh and Rs 5.85 lakh (on-road Delhi). 

Alternatively, dealers will be offering discounts on models like the Maruti Celerio and Renault Kwid, so you could even consider those. 

The Maruti S-Presso is the most affordable car in the country, and as a city runabout, it is a good option. It is a very user-friendly car thanks to its peppy yet fuel-efficient petrol engine; the clutch, gearbox and steering are light; and due to its high seating visibility, all around is good too. Moreover, spare parts costs are likely to be inexpensive and being a Maruti, servicing will be a relatively fuss-free affair. If you like the S-Presso for what it offers, go for it.

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. 

For a budget of Rs 5 lakh, there aren't many automatic new car options available. 

You could opt for a Maruti Suzuki S Presso VXi AMT, which would serve your needs. But as you need to carry four family members during your occasional weekend use, we would recommend upgrading to a Maruti Suzuki Celerio 1.0 Petrol VXi AMT. It is a bit more spacious and upmarket. 

However, yes, given your limited usage and need for passenger room, we would recommend checking out a used car
