Passo is 1000cc not 660cc
and 5 year old JDM car is better than zero meter cultus in any way u wanna compare... drive is better, more comfortable, better looking, more features, economical, less noisy than KHRRRRRRRR sound of cultus.. and yes if u wanna take into account theft, cultus has way more probabiltiy of getting stolen or snatched as opposed to passo
But then again, if having MT is a must requirement for you, then cultus should be the choice for u..
