My monthly running is not more than 650 km, and I am planning to buy the Mahindra Thar Roxx. I intend to keep the car for at least 10 years. I am confused between choosing a petrol or a diesel variant. Considering resale later and the future of diesel in India.

We recommend the Mahindra Thar Roxx petrol automatic, with your 650 km a month and a 10-year plan, it will be easier to live with and safer against policy changes. Your running is low, so the usual fuel savings of a diesel will not make up for the higher buy price and upkeep over time. The petrol is quieter and smoother in daily traffic, has lighter controls, and you avoid the diesel’s emission filter issue that can pop up with lots of short city trips. 

Looking 10 years ahead, petrol is also the safer bet for resale, especially in big cities, and you don’t have to worry about the 10-year diesel limit like in Delhi-NCR.

For your usage, the petrol automatic is the stress-free choice you’ll enjoy every day and won’t worry about keeping for a decade.

Hi Team, I am from Bangalore, and I am planning to buy Mahindra Thar Roxx AX7L Diesel AT 4x4 in October 2026, hoping to get festive offers. My annual running is around 12,000 km, with 70% of it on highways. If I use my car only on weekends in the city and occasionally (once every two months) for long highway drives, will that be enough to avoid DPF-related issues? With the upcoming Isobutanol fuel blending, do I need to be concerned? Are Mahindra diesel cars compliant with this fuel?

With 12,000km a year and 70% highway driving, you are actually the ideal diesel owner. The Thar Roxx AX7L Diesel AT 4x4 is a great choice for your usage pattern, and you should not be worried about DPF issues. The DPF system needs sustained higher exhaust temperatures to regenerate, and your regular highway runs will take care of that naturally. Even if you are only using the car on weekends in the city, as long as you are doing occasional long highway drives, the system will regenerate as intended. The real DPF problems tend to occur with cars that are used exclusively for short, low-speed city trips with no highway running.On the isobutanol front, there is nothing to worry about. Isobutanol is being considered as a diesel blend, but it is not a major policy direction like E20 petrol. Mahindra diesel engines are designed to handle the fuel blends available in the market, and there is no evidence to suggest that isobutanol blends will cause any issues. The bigger concern with diesel ownership is always usage pattern, not fuel blends.The Thar Roxx is a very capable and enjoyable SUV, but it is worth being aware of its limitations. It is not the most practical family car, and the ride can be a bit firm on broken roads. But for your usage pattern, it is a solid choice. If you are looking for a more practical alternative with similar diesel capability, the Mahindra XUV 7XO Diesel AT is worth considering. It offers a more comfortable ride, better practicality and the same strong diesel engine. But if you want the Thar Roxx for its character and off-road capability, your usage pattern supports that decision.

Hi team, I am considering buying the Maruti Suzuki Jimny because of its compact dimensions, good looks, and SUV feel, mainly for city driving and short road trips. However, I am concerned about its low sales and resale value. The Mahindra Thar Roxx seems too large for city use, while the Mahindra Thar feels cramped in the second row. Please suggest whether I should consider buying the Jimny. Is a facelift expected soon? Should I wait for the 4x2 variant if it is going to be launched?

The Jimny is a genuinely likeable car with its compact dimensions, rugged looks and proper SUV feel, and it is well suited to city use and small road trips. However, your concerns about low sales and resale value are valid. The Jimny has not found a large audience, and that does have an impact on long-term ownership confidence. The Thar Roxx is indeed much larger and less city-friendly, while the standard Thar remains cramped in the second row, so neither is an ideal alternative for your usage.As for a facelift, there is no confirmed timeline for a major update, and waiting for a 4x2 variant is not advisable unless you are specifically looking for a more affordable, less capable version. The Jimny’s appeal lies in its 4x4 capability, and a 4x2 version would dilute much of what makes it special.If you love the Jimny for what it is, you can still go ahead and buy it, but do so with the understanding that resale value may not be its strongest suit. If that is a major concern, you may want to consider more mainstream alternatives like the Brezza or the Kylaq, which offer better ownership confidence without the same level of off-road character.

Which car should I buy under a Rs.13 lakh on-road budget? I don’t need fancy features in my car. I want a good engine that doesn’t feel laggy, is low maintenance, offers better safety, and has good mileage. Should I wait for a flex-fuel car, considering the current scenario is not good, or should I buy a second-hand diesel car? No sedans.

Go for the Maruti Suzuki Brezza. It fits your brief perfectly: it has a strong, naturally aspirated petrol engine with no turbo lag, low maintenance costs and a proven ownership record. This Maruti Suzuki car has features on offer that cover all the expected basics with none of the fancy, flashy bits. Maruti’s service network and affordable parts make long-term ownership and maintenance easy. Wait for just a month, as an updated Brezza is due to arrive. On flex fuel, there is no need to wait. India is currently at E20, and there is no set roadmap as yet for higher blends. In any case, modern engines are engineered to handle E20, and the impact is mainly a slight drop in fuel economy rather than any major reliability concern. Maruti has also gone on record to state that their E20 engines are material compliant for slightly higher ethanol blends, so from a reliability point of view, you will be fine; however, mileage could drop. A used diesel is not the right call unless your running is very high and you are comfortable with the risks of DPF issues and higher maintenance as the car ages. For most buyers today, a good petrol SUV is the safer and more sensible long-term choice.
