Very good economical car. I had a diesel G 101 and it did 15 + kmpl. You can get an idea about the car from here. Also you can find lot of details searching AL.
Since it is now 20 + years old you have to keep minimum Rs. 100,000 for repairs unless it is very good specimen. Check flow board, wheel arch area, doors for corrosions. Most of the time you may have to overhaul the engine. Parts are still freely available. Dash board and door panels are hard to find if I remember correctly. You can get an idea about prices from here.
