Grand Vitara over Seltos?

So we are looking to buy a 2nd car, and we have zeroed in Grand Vitara (strong hybrid) over the other competitors.

The decision was primarily based on the mileage as the primary usage of the car will be to travel from home to work. (Delhi - Gurgaon, 30kms one side)

Nexa is currently giving a discount of around 1.8L on Grand Vitara, due to which we had to let go of Hyryder. (Doesn't make a lot of sense to purchase the same car for around 2L extra).

We currently own a Glanza, which we plan on using as a secondary car.

The cabin experience of Seltos was definitely way superior than that of GV/Hyryder, but even the NA engine with CVT won't give us a good mileage in bumper to bumper traffic!

Just wanted to ask your opinions on whether this is the right decision or not, considering it is gonna be a very big investment from our end.

Fellow redditors who own Grand Vitara/Hyryder, please leave your reviews as well. Thank you :)
