I am looking to buy a car for my family of 5 and live in a Tier-3 city. My usage is quite low, at a maximum of around 500 km per month. I am currently confused between the Tata Punch and Tata Altroz. I am also unsure whether to choose petrol or CNG, especially with the ongoing discussions around ethanol blending and the possibility of E25 and E30 petrol in the future. Given my low usage, which car and fuel option would you recommend for long-term ownership? Also, should I go ahead with the purchase now or wait for further developments regarding ethanol-blended petrol? Please consider comfort, practicality for a family of five, reliability, running costs, maintenance, and long-term ownership while suggesting the best option.
Between the Tata Punch and Tata Altroz, the Altroz petrol is the better fit for your needs. With a family of five and very low monthly running, a petrol car is the right choice - CNG cars only make sense when running is high to justify the extra cost. The Altroz is the better family car here: it offers a more comfortable ride, a wider rear seat and a more spacious cabin than the Punch, which matters on longer journeys with three at the back.
On ethanol blending, there is no need to worry. Modern petrol cars are engineered to handle E20, and there is no official roadmap for E25 or E30 in the near future. Go ahead with the Altroz petrol.
