Iam planning to buy. four wheeler for taxi purpose.. which would be the best in relation to performance,mileage, less maintainence and some of the drivers suggested me to have Indica v2 , nissan micra, maruti ritz....please suggest which would be the best . thanking you

Indica V2 is still a very good choice but Micra may not suite as taxi due to various reasons. I think you are looking for hatchback taxi, have you tried to check Toyota Etios Liva, its entry level diesel variant gives 22kmpl mileage. Downside is that its little costlier than indica .
