Overall, It's a good car. I have driven it for 6K+ kms in city as well as on highways. No such complain.
Best for highway driving. I'm satisfied with this car till date. I purchase this car in July 2017. Revotron XZ(O).
Getting average fuel economy of 15.6Kms/liter after 3 serivce ( 75 % City + 25% Highway)
On highways, fuel economy ranges from 17km/liter to 20+kms/liter.
Sturdy build quality. But you may face lock issue which i faced in begning. Company changed same under warranty
In short, not a bad option to choose from existing choices, considering cost, quality, safety ,milage etc.
