Q. What is the mileage on Highways and Maintenance expenses for Vento? Are there other cars which I can consider are better than Vento in the same price range?

Mine is Vento highline 2013 model. On highway It give me 22-23 when you go on 80-90 kmph, and will give you around 20-21 when you go on till 110. Maintenance will be 13K when you go for VW showroom servicing every year, and will cost 6-7k when you get it done outside work shops. Parts will be costlier but will last long. I loved vento than others.

Maintenance cost as in other answers.petrol option is Honda city.Both for manual and automatic. Diesel manual you can trust verna crde.Diesel at verna has introduced 7 speed replacing old 5 good ,long term issues we have to see .But it's worth. you have to stretch you budget to higher side.

To be honest I am not checking on the mileage. But I guess I get a decent 12/13 for city commute with a occasional highway trip once a month included.
