I too have Ertiga CNG. Bought in October 2020. My car gives 200km on Highway and ~140km in city on CNG. great space in the car. This car has great pickup even in CNG.
Aapki advise pe hi Maine ertiga cng le li.. aur 9 mahino me 22k km bhi complete kiye he.. and I am very much satisfied with this vehicle. Truly amazing budget segment MPV. Ravi sir as you know I was going for triber... but you asked me to go for ertiga.. The only concern is it's built quality and plastic material otherwise. This vehicle is Made to cruise around max 100 or 110km per hr. Not more than it. The feature it's missing like cruise control and I feel some time 6th gear hona chahiye jab aap highway pe ho..
The best thing about it is the 3rd row is such a comfortable one for about 130 km in the night ,make it double in the day and it's still comfy.hard to master that
Ertiga is really a very good choice...i hv an Ertiga 2020 model.nd this is really a very nice machine...budget friendly...u can hv a better boot space...seating is so cool...cng or petrol is equally feel.
