Goto expo centre tomorrow. See if u can find a 2019 Alto AGS in your budget. This should be around 2 million. (Suzuki used car mela)
Else look for a Mira, Alto, Move etc or a 660 Japanese Alto 2000/2004 if budget is a problem.
You can swap a new engine in a Japanese Alto, a local alto transformation to 660 needs slight alterations. But it's doable
A decent local alto can be sourced in rs. 325,000 to 475,000 for 2002/2004 cars. (Iguess).
A Japanese similar alto can cost around 700 to 900k.
That would be automatic and 660 by default. Might need engine replacement if in bad condition since it would be 20 years old.
