Brother from your comments it is clearly visible that you're inclined towards cuore better get your hands on a clean cuore
It totally depends upon your requirements that which car suits you , i want a bigger car in which i can squeeze some friends and go on trips so i'll be needing more cabin room ...
i also had a cuore 06 at my home and no doubt cuore is fantastic
about consumption , its obvious that coure is 850cc while cultus is 1000cc so cuore will be more fuel efficient
about toughness i cant say anything as it depends upon angle at which the car is being hit. ALLAH bless us all and keep us safe
