I have driven series of Suzuki(Ex. Maruti Suzuki) cars beginning with Omni & 800 and then next one was Zen, Dzire(Petrol) & finally Baleno. Among these models, I can say that Dzire is the most economical model with reasonable price bracket & all benefits of a sedan car.
The only issue I faced till date in Dzire is underrated Clutch which clearly refuses to engage when trying to drive uphill with loaded car. I had to offload all passengers and make them push the car along with aggressive acceleration to climb the steep hill road. Whereas my friend could easily make it in his WagonR. Hope Suzuki have noticed this flaw and done required changes.
