Q. Does Maruti Suzuki Baleno has rear seat comfort with more space and good for tall drivers. Can we use this car for long drives?

Yes, You can very well use it for long drives. It is also comfortable both in front and back seat even for tall persons. Vehicle pick-up is good and can give you a mileage up 25 (petrol version) in highways (maintaining the correct RPM)

Baleno offers pretty good leg room in the back seat and the headroom is descent However if you are more than 6 feets then there are chances that your head might hit the roof while going through bumps . Suspension is good but one can feel in the bumps in the road inside the cabin

Yes. It is very comfortable and suitable for long journeys. Only issue is less safety features than the recent ones.
