Tell us your prefrences, location where you will drive a Car, area where you live, family size which will use a car? In 1.9 million budget you have alot of decent options.
Aqua(bad ground clearence, good resale, hybrid, overall great package)
Honda hybrid fit ( great car, more customization, touchpanel to control Ac ,multimedia and other dashboard stuff, market and parts availability is bad)
Fielder hybrid ( it is pentrating in pakistani market, overall full package. Spacious as compared to other cars available in market. You will get good car for 21to21.5lac)
Another option is famous prius, but you will not get it fresh in your budget.
Nissan juke is another option in case you want suv but no resale. Less spacious same as aqua.It has semi hybrid sort of technology(don't know much about this)
