Here is what i think, and i will comment on stuff i am sure.
A) Kia Forte is a C-Segment car, biggest car among the 3. CKD quality. The highest FC  among the 3. Resale value is about the same as a Fiesta.
B) Ford Fiesta is a B-Segment car, same as a VIOS. CBU quality. FC consumption, i am not too sure. DSG gearbox, i think FC should be very good. Resale value pretty much meh.
C) Toyota Vios is a B-Segment car, average of the two. CKD quality. Proven very good FC. My bro is driving one. So i can vouch for it. Good resale value.

Now the question is do you need a car with boot space? Would a larger car be better for you? Or you looking for resale value? Reliability for 3 cars, they are all good. Hardly read any bad comment among them.
If you need a bigger car with boot space, then it is forte.
If you need resale value and proven car, then it is Vios.
If you want a car with plenty of safety and latest tech, then it is Fiesta.

Personally, i would take Fiesta given the 3, but that is just me.

since u not realli good in automotive,better take city or vios,but i must say vios is a veli boring and overpriced crap...city is must better wif the same price

Well, if you go for Kia or Ford you might go hunting for spare parts, which might be a bit difficult.

To give you an example from Renault (no clue how it is with Ford or Kia): I can easily get the spare part (with some waiting) from my SC. For example RM 490. In Singapore I was quoted S$135 at one spare parts dealer who has one, another quoted me S$100, but I'd have to wait around 2 months. Chop shop in Singapore (after some searching... such a cheap part they may not be bothered to even search, so they simply say they don't have) had the part for S$50. In Europe it costs like 30 Euro new including shipping, but customs might mean trouble (dunno). Waiting is another thing that might happen. If they don't have stocks here...

You also might only get original parts here, so it is quite expensive.

With a Toyota or Honda the hunt will probably be less troublesome.

However you get the nicer, better, more refined car. Toyota uses ancient technology, but being ancient means they have perfected it. It _should_ last, but the gearbox was already used by the Romans etc.

DSG is the latest tech in gearboxes... basically it is a manual gearbox with 2 sets of gears and 2 clutches. Driving it is a bit different from driving a normal auto (at least the VW I drove will roll back when you are in D and not on the gas pedal), but the fuel consumption will be lower and the performance is better (6 gears vs. 4 so the engine can be kept in the optimal rpm range for what you want to do), the gear changes are faster and smoother. Go to YouTube and have a look how such a gearbox works.

CBU is completely imported from a foreign country. CKD means they deliver the parts for assembly in Malaysia, some parts might be made locally. Means lower taxes but the fear that someone in Malaysia screws up and the quality is lower.

AFAIK A segment means submini... very small cars. Viva, VW Fox (mh... bad example as it's not known here) etc. A small hatchback or the saloon based on it is in the B segment. Think Polo, Fiesta, Vios (based on Yaris (Europe)/Vitz (Japan)), Swift, ... C segment is something like a Golf, Forte, ... then D segment would be Passat, Camry, Citroen C5, BMW 3 series, those sort of car.

Looking at the sales figures of the Fiesta though it actually doesn't do that bad. Means SC will be experienced (my SC knows the Kangoo since there are quite a few of them on the road, and they all come to the same SC), parts might not be that big of a problem and perhaps non original parts might be imported one day. Resale value might change if the car becomes popular, and... well, it could.

In Malaysia... Fiesta need to sell more n most important is their service center need to be better prepare... A lot of complain on their service so far.

I would say it is B segment, but who cares, really. What counts is if the car suits you in terms of space, quality, ride etc.

The price for a new car... could happen. I believe they have raised the price already. Resale price too. It all depends on how much people want the car... what price they are willing to pay. If it becomes popular, then yea, they want the thing, and thus are willing to pay more for it. Not popular, price will be low. But how it will be in 5, 10 years, who knows. It's like buying and selling stock...

You might want to read the respective threads of the cars that you consider. You'll be finding complaining Vios owners, complaining Fiesta owners, complaining Forte owners. Vios owners will probably have more options though, there are more SC and workshops that can deal with the car.

My main advice is to drive them all as much as you can and under realistic circumstances and to listen to the owners (not that they'd say their car is crap compared to the competition, that would mean they'd have to admit they have made a mistake. Not everyone would want to do that. And not everyone has had the opportunity to drive the competition). Also, every car will have it's strong and weak points. You'll have to know yourself what is more important to you.

I drive a Citroen Xsara II 1.4(M) from 2002 and a Renault Kangoo I Ph 2 1.4(A) from 2005.

Been in a Toyota Aygo (pretty stiff and unrefined, loud, cheap materials, but reliable) and Yaris/Vitz (Vios hatchback). The Yaris felt cheap and a bit loud (IIRC definitely inferior to the Xsara, and I believe also to the Kangoo, though materials are better than in the Kangoo). The ride felt unrefined IIRC (been a while).

I have only traveled a few hundred km in some older Fiestas (I think one of them was the previous gen one). They felt like proper cars, in small. Other Fords as passenger... S-Max, old Mondeo (early 00s I believe), mid 00s Focus wagon and the older Fiesta. They were all decent cars IMHO.

I did drive a first gen Ford Ka (not really relevant but fun to drive except for the Myvi'ish manual gearbox. Imagine a small 4 seater go kart, but it felt decently made with not too bad materials... must have driven 130-140 and didn't felt scared) and the latest Ford Galaxy (7 seater van, something like an Exora). The Galaxy was very well made, looked really good and felt pretty good. I really liked the ride, not as stiff as a VW (Touran!), but also not wobbly at 180 km/h (the Touran is more planted at those speeds, but I only didn't go faster cause I didn't want to torture the engine). The engine was the smallest diesel, which was actually powerful enough. Manual gearbox was pretty good, totally unlike Myvi or Rusa. The Fiesta is much lighter and has more hp

I liked the DSG in the VW Cross Touran, totally unlike that rubbish 4 speed auto gearbox that Renault used in the Kangoo. Miles apart. While I expect the Toyota unit to be better I doubt that it can compete with a DSG, even though in the Fiesta it lacks the paddles.

I also spent some time in the latest Opel Corsa, which is probably the closest competitor to the Fiesta. It's a good car. My Kelisa driving cousin from Singapore drove it several hundred km one day, and she liked it (more than the Xsara ). I did a short test drive, it felt well made (interior is good, much better than Myvi and Saga), a bit stiff suspension but nothing too bad. However I really hated the driver seat, perhaps I should have spent more time adjusting it but the seating position was bad. Not sure how Corsa and Fiesta compare, but I guess both are a decent example for a small mid budget Euro hatch. In comparison a Polo is a bit more expensive over there, and perhaps a bit better. Here however... oh well.

My only experience with a Kia was with the cee'd Sporty Wagon and tyres with spikes, on snowy roads chasing after moose. (so different car in very different conditions). It felt quite a bit cheaper than a Golf, but well, it is a quite a bit cheaper car. It was in all aspects inferior, but still not too bad. You get what you pay for. I'd say better than the Xsara (however I enjoy the not too stiff ride of that one on uneven surfaces, sometimes contis feel just too uncomfortable... I'm looking to you, VW), but it's also a newer car.

As I, like many, haven't had real experience with the cars in question and your taste and preferences may be totally different from ours, please do drive them. In some threads though some report who have driven both Vios and Fiesta, and I believe they preferred the Fiesta.

Not more quietly (that's the noise insulation they use...), but well, faster. Very fast. It's what Nissan uses in the GT-R. I thought the gearshifts were very smooth in the Touran, except when using the paddles for downshifting, then there was a slight jerk (going to quite high revs though).

Also since a DSG is basically a manual gearbox using real clutches it behaves a bit like a manual one. Low FC compared to the regular torque converter auto gearboxes, but also rolling back when standing on a hill while in drive (at least the Touran does that, however I think there is a feature where you have to press the brakes a bit harder while standing still, then the car will engage the brakes until you press the accelerator. Not sure how Ford solved it.

I still think Ford is foolish for not adding 2 paddles (how expensive can that be?!).

@Jim.tan: Is it true that the sport also has 7 airbags now?

Only polishing his car once doesn't mean that he doesn't care about it mechanically. You can still service it on time, every time, in the SC. Fix any problem as soon as it arises. etc. But yeah, 280k is a lot.

Ah I see, so they don't even look at the car. That explains it.

so difficult to choose, take vios lah,

there, close this thread please, it is a repeat of the never ending saga of the RM80k range.

would you be interested to buy a second hand civic? 2.0 2006 model.
