I’m looking to buy a new or used car with a monthly running of about 2,000 km (mostly city with a few Mumbai-Pune trips). The car will be mostly chauffeur-driven, so rear-seat comfort and smooth low-speed performance are important. Daily use will be for 2-3 passengers, but I need occasional seating for six. I prefer Hybrid, Diesel, or Electric. My priorities are comfort, reliability, low running costs, and strong service support. My budget is around 25 lakh. Please suggest 3-5 options and include used choices if suitable.

With your extensive usage, we cannot recommend an EV, as you would have to charge it frequently, and that is not good for battery health. In your budget of Rs 25 lakh, there aren't any 6-seater hybrids, either; your only option there is to move up to the Rs 30-lakh-plus Toyota Innova Hycross or Maruti Suzuki Invicto - both of which are excellent choices. 

In your budget, the best option is the Kia Carens Clavis diesel. It's well equipped, comfortable and surprisingly spacious for its size. Plus, there are both six and seven-seat versions, so you can choose which configuration suits you best.
