vitz is too low , kei has many features which we can only find in expensive cars like ABS , airbags,auto etc ,it may be underpowered or not i cant say anything but didn't feel it in test drive on petrol. passo has good ground clearance ,both 2008 kei and passo are in my budget so race is between city 2005/2006 passo and suzuki kei ,yes i know these are three different class of cars but still any help will be appreciated
