Hi guy25,
Yah, my friend did encountered some bad experiences when buying a
2nd care from dealer too. Seems like no1 can be trust nowsday,
haha. Yup, agree that most on classified ad are dealers, so do
watch out if buy from them.
Anyway, I didn't get it brand new, bought it from the owner direct!
Therefore, was cheaper than those on the 2nd hand car market. Got
it last Oct, exactly a yr ago, at 47k flat, parf at 9.5k. When I
bought it, there's still 6 yrs 8 mnths left. So by calculation, in
80 mnths I lost 38.5k, which work out to a depreciation of not more
than 5.7k a yr without interest.
Beside the normal servicing, the car is alrite, didn't spend much
unneccasry things, except that i change the tyres and brake pad the
moment I got the car (Wear out by previous owner). I change the two
suspension mounting (Wear out by previous owner also) too, and to
my relief, it cost less than $200. Guess one advantage of March is
the easy to get spare part. Other than these few items, the rest
are okie so far. No major problem so far.
My car mileage is currently quite low still, heh, so I dunnoe how
it will be when it 200,000km or more. But of cos, I'm sure you
cannot compare a 1000cc car to a 1600cc. That's just too much
different. And from my personal pt of view, cars like toyota,
honda, nissan and mitsubishi should not have any problem lasting 10
yrs even if they're cc are small.
Yup, the new nissan march is a 1260cc bettle-like shape cutie.
Looks cute, haha, and best still, its stated 1L of petril is able
to travel 19km! How's that!!! Me hope my March is like that
too.
Maybe you can test drive the car 1st b4 deciding further. Like i
say, a good 1000cc car except for the fuel consumsion. You might
not get used to it too as you are used to driving a 1600cc car.
When I 1st drive it, not use too, but after a few mnths, got very
use to it. 
Hope you find one car that you enjoy driving soon. Need for infor
feel free to ask me, I'll try my best to assist or help if I
can.
