I used my Ertiga for so many times for long journey. At least I completed for 3000KM in return to my home town Bhubaneswar. Last time in May 2017 I had been to Kathmandu, Pokhra, Chitwan National Forest of Neapl (self driven) that is about 3800KM. But I never faced any problem on my way. So Ertiga deserves to get 100 marks out of 100. Regarding mileage and maintenance it is incredible.
