The Kia Sonet adds Brake Assist, Anti-Theft Alarm, Traction Control, Anti-Theft Device and Anti-Pinch Power Windows. The rest of both spec sheets is shared.

Which one should you buy?

Buy the Kia Sonet if you drive mostly in the city, you want the lower running cost, and you would rather keep the ₹2.35 L for your down payment than spend it on features.

Buy the Tata Curvv if you do regular highway runs, you carry luggage or a pram often, and you want Anti-lock Braking System (ABS) without waiting for the next facelift.

The one thing that settles it: Tata Curvv offers Child Safety Locks.

Before you sign anything:

Ex-showroom price is not what you pay. Add registration, road tax, insurance and handling, and expect the final figure to land ten to twelve percent higher. Road tax changes state to state, so a car that costs the same in two cities does not cost the same to own.

Ask the dealer four things before you book. What is the current waiting period for the variant you want. What is the on-road figure.

Then drive both cars back to back on the same day, on a road you actually use. Take your family. Put your usual luggage in the boot. Most people decide in the first ten minutes, and it is rarely for the reason they expected.
