If the badge is enough to convince your family that it isn't a Maruti Suzuki, and you would like to purchase the Toyota Glanza, then go right ahead, because it is a very capable premium hatchback. Its 1.2-litre four-cylinder petrol engine is one of the smoothest and most efficient around, as you no doubt know, and it is also quite well loaded with features and spacious as well.
However, since you do a lot of highway driving, you should also consider the Toyota Urban Cruiser Taisor, which, once again, is a Maruti Suzuki Fronx with a Toyota badge.
You might have to up your budget a bit here, but the advantage is higher ground clearance as well as the option of the punchier 1.0 Boosterjet turbo-petrol engine, which is efficient, but will give you a bit more punch out on the highway.
