Q. What is the advantage of Tata Hexa AT over MT version?Which one to buy?

AT only... faster pick up, easy overtaking, better braking as it shifts down faster, very comfortable in heavy traffic, both hands on steering give you better control of the beast. Go for XTA . Manual will give you 1-2 km more mileage overall but not the other things I just mentioned in comparison to Hexa automatic. Thanks

In manual transmission clutch is quite hard and automatic transmission works well and quite fast. It is really good in compare of xuv500 automatic
