ok here's my 2cents worth
build quality:
sunny - made in japan, should be ok
vios - thailand, not very good, seems to be a lot of problems here
and there, check out the vogs forum
city - thailand, but could be better than vios, why? cuz it's
exported to japan as fit-aria. if it's good enough for japan,
should be good enough for us, no?
comfort/suspension:
sunny - never found sunny to be comfortable leh..interior small for
that kind of exterior size
vios - typical toyota soft suspension, very uncomfortable if corner
aggressively, cramped interior
city - vtec has a sportier suspension than idsi, esp the new
face-lift since it's been tweaked even further(the original vtec
has already one layer of changes from the idsi version)
engine:
sunny - variable valve timing, but feedback from owners seem to be
there doesn't seem to be any difference, you should check out sunny
forum
vios - variable valve timing, good power for its weight
city - vtec, effectiveness is more than vvt in terms of power wise.
vtec engines are also very fuel-efficient when operating below vtec
kick in
fc:
sunny is infamous.
vios - fc good
city - should be close fight with vios
looks:
sunny if you like ah-pek look
vios - facelift looks worse actually
city - facelift looks much better
price:
sunny: made in japan at that price is good
vios: cheap lah
city: priciest, about same price as altis, but what you get is
better cabin utilisation, big boot, efficient cvt(if auto), wheel
base same as vios, better suspension.
ignis sport is slightly different from the 3 here cuz it's 3
door(incovenient or sporty depending on how you look at it), no
boot, dated interior look, small size, but you get a rev-happy
engine, close gear ratio, long exhaust, sporty suspension, forged
pistons and quite a lot of mods compared to a 'normal' car.
