Hello,
Is CNG as an option available in Chennai. If yes - then suggest to consider in
> Hyundai Xcent Prime CNG
> Maruti Dzire Tour S CNG (getting launched in coming days)
While Hyundai Xcent will still have advantage of bigger boot space even after CNG and slight better legroom space as against Dzire.
If Diesel car is what you considering and considering fact that Diesel cab operator have atleast 150 Kms a day drive means 50000 Kms a year drive then in that case suggest to consider in Toyota Etios Diesel as been the best buy based on boot space, in cabin space and assured low maintenance cost.
Should help !!
