Which Car Has the Lowest Overall Running Cost?

Looking for a compact hatchback that can squeeze through narrow lanes and handle stop-and-go traffic easily. My daily drive involves crowded market areas and tight parking spots. Between WagonR, Grand i10 Nios, Tiago, and Celerio - which one's the most practical for urban conditions? Fuel efficiency matters too since I'm stuck in traffic most days.

My current car's fuel bills are killing me honestly. Thinking of switching to something more practical that won't hurt my wallet every month. These four seem like the most sensible options for city use with decent mileage. Anyone made a similar move? Want to know which one actually delivers on the running cost promise in real-world conditions.

Looking for suggestions on a fuel-efficient SUV. I clock about 2000km monthly, mostly highways and rural roads. Used to love my old Duster diesel for its amazing efficiency and solid build quality. Now with diesel options reducing and hybrids becoming common, I'm confused about the best choice. Need a reliable SUV that won't burn a hole in my pocket with fuel costs. Any advice from long-distance drivers?
