my opinion, go for the fit, i'm currently driving the 1.5l
version.
1) lots of aftermarket parts both here and japan, big community in
Singapore(SWOG)
2) fuel efficient car.
3) small, easy to drive/park, extremely light steering wheel,
lovely vtec sound from engine when reved.
4) seats foldable to create more space.
5) cute looking.
6) value of hondas are more than mitsu
anyways, this is kinda one sided, but the colt's interior is nicer
than the fit. I had the same feeling when deciding between the fit
and the ist. try test driving both the fit(kah motor, test drive
the jazz) and the colt. then decide one which one you see yourself
driving everyday.
