Have you bought or currently looking to buy one
1. Being an old car now, it will deliver 10-11kmpl in city drive, 12-13 on long drive with petrol. for Cng expect 150-170km per tank
2.There were earlier models with distributor, newer models had coil packs
JXR (simple model with power windows) JXL (loaded version) and GTi (1600cc engine)
3. Maintenance is bit tricky. a good mechanic can easily diagnose faults. Normal maintenance includes oil change along with air filter, oil filters. Baleno's air filter housing is bit loose. You should get it cleaned every 500km and changed every 3000km. wont cause any problem. Spare parts are available, though some are bit expensive than other cars of same age but who needs spares every now and then
