I have a 2023 Grand Vitara AT (non-hybrid) and spend around Rs. 12-14k per month on petrol. City mileage has dropped from around 13 to 10 kmpl. I have solar at home, so EV charging will be almost free or cost a maximum of Rs 3-4 per unit. I'm confused about whether to replace the Grand Vitara with an EV or keep it and buy a Tiago EV for daily city use. Or am I overthinking the fuel savings? Should I just keep the Grand Vitara and avoid buying a second car altogether? Would like to hear from people who have been in a similar situation. What makes more sense financially in the long run?

You are not overthinking the fuel savings, but the decision is not purely about fuel cost either. At Rs 12-14k per month on petrol, your running is high enough that an electric car makes strong financial sense, especially with solar at home.
The bigger question is whether to replace the Grand Vitara or add a Tiago EV. If your daily usage is mostly city driving and the Grand Vitara is not being used for regular highway trips or family duties, replacing it with an EV is the cleaner financial decision. You eliminate the petrol expense entirely and avoid the depreciation and maintenance of a second car.
If the Grand Vitara is still needed for highway trips, family use, or you simply enjoy owning it, then keeping it and adding a Tiago EV for city use is a sensible approach. The Tiago EV is a cost-effective city runabout and will take the bulk of your daily running, while the Grand Vitara remains available for longer trips.
Financially, the biggest savings come from replacing the Grand Vitara with an EV. Adding a second car makes sense only if you genuinely need both vehicles. If the Grand Vitara is not essential, do not keep it just for occasional use.
