Using 2016 Civic X 1.8, and getting 12 KM/L within City travel without any issues Alhumdullillah. You just have to get the car checked from dealership in order to ensure that it doesn't have the faulty parts or have been replaced i.e, steering rack and AC evaporator. A relative is using a 2017 Civic without any faults while my friend faced steering rack issue in 2018 model so just look out. The price difference between a 2015-2016 mint condition, low mileage Rebirth and a 2016-2017 Civic X is just 3-5 Lac which I think is justified. Rebirth is a good car itself but not worth 30-31 Lac which 90% of owners are demanding right now for a full genuine low mileage car. A friend's Rebirth faced an issue at just 40,000 KM's of ball joint due to which dashboard was shaking at 30-40 KM/H so no car is 100% fault-less. Don't go for those Civic X which are in 30-31 Range, a sincere advice.
