Sweety
•2dHi, I am planning to buy a car for 10 to 12 lacs. I am confused, I should buy diesel or petrol, my daily running is 50 kms, including city and highway drive, and on weekends, there can be highway trips as well. Due to the DPF issue, I am confused whether I should buy a diesel car or not. Also, please suggest the best car, I am planning Sonet HTK plus or Mahindra 3xo AX5.

With 50 km a day, a mix of city and highway driving, plus weekend trips, petrol is the safer pick for you. It avoids DPF worries. Modern diesels work fine if you do steady highway runs for 15-20 minutes a few times a week, but if your driving is often slow and short, the filter can clog, and you will see warnings.
Between your two choices, pick the Mahindra XUV 3XO AX5 petrol. It fits your budget and usage better because its turbo-petrol engine feels stronger on highways, so overtaking is easy even with passengers and bags. It also rides well over rough patches and feels steady at speed, which suits your weekend runs. In the city, it is easy to drive and not hard to park. If you are opting for the automatic, the torque-converter gearbox in the 3XO shifts smoothly and makes city driving stress-free.
Know the trade-offs. The 3XO’s boot is not the biggest, so fitting two large suitcases plus extra bags may be tight.
If you mostly drive in the city and carry a lot of luggage, the Kia Sonet HTK Plus petrol is the better alternative. Overall, for your mix, the 3XO AX5 petrol lines up best.
