I got a Cng fitted i10. Use it daily for 40 kms up n down.
Its a nice comfortable car. Practical for city traffic and maneuvering.
Pros:
1. Good mileage
2. Low maintainence
3. Responsive steering
4. Good suspension
Cons
1. Upholstery quality can be improved
2. No android or apple car play
3. Airbags in top variant only
Overall I'm happy with this car. Being driven in delhi where cng stations are in plenty cost of driving is equal to bike.
Heater and AC is nice but require regular maintenance.
Hope this helps
