My requirement is a 6-7 seater vehicle. For low maintenance cost, I can go with either CNG or diesel car as my monthly running is 1000 km and occasionally it can be as high as 2000-3000 km monthly. I am from Pune and my frequent outstation routes will be Mumbai, Kolhapur, Latur and Kokan area (ghat sections). Also, since I can rent it out as self driving car and I will own upto 7-10 years. I have owned Alto, Wagon R, SX4, EON and i20 active disel. I have mentioned vehicles so that you can understand my driving and owning experience.
Given your requirements, the Maruti Suzuki Ertiga CNG is the most sensible recommendation. Your monthly running of around 1,000 km, with occasional spikes, does not justify a diesel, especially with the higher purchase cost and maintenance associated with modern diesel engines. The Ertiga CNG strikes the right balance between low running costs, reliability and practicality. It is a proven 7-seater with a comfortable ride, good service network and low maintenance costs, which is important given your plan to keep the car for 7-10 years. The CNG system is factory-fitted and well-integrated, making it a far better option than any aftermarket CNG installation. The only drawback is the reduced boot space with the CNG tank, but for your usage pattern and occasional rental plans, the overall cost savings outweigh this limitation. If you need more space and comfort, the Maruti Suzuki XL6 CNG is a good alternative, offering a more premium cabin and captain seats in the middle row making it a strict 6-seater, but the Ertiga remains the more value-driven choice. Alternatively, there is also the Toyota Rumion, which is Toyota's version of the Ertiga so if there is a lower waiting time, you can check out the Rumion too.
