However it's very late but I m writing it for other guys who will ask same question
Suzuki liana is not a bad car people have bad experiences due to lack of knowledge regarding this car more over most of machines don't know much knowledge about this car
First choose car very carefully don't go to some peepaa condition car to save money always buy a well maintained car most often you get in 550000/rs to 750000/rs depends upon model and condition.
If you get problem take your car to some experienced machine
Suzuki liana has a slow resale
If you have budget of 700000/rs to 750000/rs then you can also go for honda city 2003 to 2005 which is mostly known as cuhaa shape(mouse)
This honda city model is very fabulous model in each and every aspect very very reliable solid good fuel economy not much expensive spare parts . Very good resale
