you can expect a price of 7.00 to 7.75. and most probably it will be a clean and perfect ride.
as for fuel economy, cuore gives very good economy. you can expect 14+ km/l in city on petrol, and 18+ on long. works great on CNG too.
cuore is 850, small car. while others are 1300c and +. they are a different category. you will not get comfort, power and stability of a big car in cuore. anyway it is simple,reliable, economical and robust. best in its class.
knowing all this, if you go for it you will not be disappointed. a clean cuore only takes, oil and filters change as maintenance.
