Only 1 car in India has ever sold 5 million units, it's not i10, Swift or WagonR

The Maruti Suzuki WagonR, Hyundai i10 (the whole series from i10 to Nios), 

Maruti Suzuki Swift, Hyundai Creta, Mahindra Scorpio, and, for that matter,

the Toyota Innova are some of the models that spring to mind when one considers the best-selling automobiles in India. 

One vehicle, nevertheless, remained at the top for an extended amount of time.

We do not refer to the Maruti Suzuki 800, which is unquestionably a famous vehicle. We are speaking about the Maruti Suzuki Alto, another phenomenon.
