If you are talking in terms of driver seat comfort then checkout WagonR Stingray, I20 Elite, Duster, Terrano, Eco Sports, Sumo Gold.
Talking on back seat:
There are very less chances that a person tall like you can sit comfortably on back seat.
Having a large leg room wont serve your purpose, coz the under thigh support is also the major factor considering "ergonomics".
If you can checkout new TATA Sumo GOLD at showroom; I think it may serve you better.
The only thing you can do is check out used car market and new car showroom for the best options. Here no one can help you better than you, coz it is an experience that can only be learned by you.
Also let us know you choices. This will help to improve TAI
