FYI Altis vs Sylphy
maintenance/ownership : after warranty over spare parts and service at outside workshops are affordable
design : they're both got their ups and downs this is up to your personal taste
performance : they're both pretty decent
rv : sylphy wouldn't be as good as altis

they're great entry level c-segments but don't have too much high expectations.
just a food for thought the mitsubishi lancer sportsback which is usually at 130k should be going for the cheap soon to clear their 2013/2014 stock, you can go and check it out

i never really had any good experience with the swift.
few friends owned them always had problems with the mountings.
see most on the road always have a busted 3rd brake light or one side of the rear lamps not working.....new cars too.
used one as a complimentary car for a week, felt it wasn't fuel economical.
that was the old model, the latest one i can't really say with any certainty but it has a smaller engine 1400cc vs 1500cc previously so better engine/fuel consumption/power? i dunno quite subjective.

insight is a decent buy since it is not a hot model, you can get one really cheap and it won't be very old.
although the car itself only has warranty for 3 years the hybrid systems are 5 years warranty.

iriz is too new with no technology carry over from any previous proton model.
so anyone buying is going to be a white mice.
Latio - at this price range the Latio is pretty much king when it comes to value. You can either choose the hatchback with impul bodykits that makes it look very good, or the sedan with the 1800cc engine. Interior design is much similar to cars of this era with airy and roomy (good space and legroom). Drivetrain tech hasn't really improved much for this model it uses some basic VVT engine with 4AT gearbox which provides decent power, reliable and with decent fuel economy but don't expect too much it is very basic BUT this sort of thing always means cheap to replace parts for and maintain when it comes to Nissan cars.

Sentra - old technology and design makes up its good and bad points. Good because old stuff is well distributed so availability is high and prices are low. Bad because old engine isn't very fuel economical and gearbox isn't very smooth, cabin design is quite cramped by today's standards. I do think the 1800cc is a good buy, a very cheap way to get 1800cc power, but like I said depends on the compromises you're willing to make.

Civic - that advert is no more, but here is one to consider. I know Civic is a good car but usually for your budget it will be the model before the 8th generation FD model which is all those 1700cc ES model (some high-spec version has 2000cc engine) but they had many issues and weren't powerful. If you can find a 2000cc ES then at least you've got a decent engine but that model many people already given up so better not touch it. Civic FD's have really high RV so don't expect many to be in your price range, look around Mudah.my for private sellers as at your price range they really go fast.

Altis - you'd probably have better luck finding a good spec Altis aged around 2007/2008 with your budget than a Civic, that is because that generation of Civic's really killed the Altis in terms of looks/design/performance but that doesn't make the Altis a bad car, yes when you're paying >RM100k it might seem you made the wrong choice but in the used car market grabbing a car like this is quite worth it, instead of a Proton Persona you've got a nice Japanese C-segment car that is reliable and cheap to maintain....power and fuel economy is quite decent too....cruising on highways going balik kampung also you'll feel more assured with your hands behind the wheel of a used Altis than a new Proton/Perodua.

Recommend:

Sylphy : This is the kind of car I'd recommend you as it is not very old, good spec and from a good manufacturer so ownership doesn't mean burning a hole in your pocket. This is a better car than the Latio and Sentra, while the Latio is also a C-segment car it feels more like a deluxe size B-segment car as C-segment cars aren't usually as bubbly and boxy, they're for junior executives/executives whom want a nice looking sleek car. Okay, the Sylphy isn't the best looking C-segment car out there but I'd rather be in one than a Sentra/Latio. Funny thing about the Sylphy it isn't appreciated well by the public so that is why it's RV sucks but that's a good thing for used car buyers like you as you can pickup a 2010 Sylphy for 2008 Altis money.  
2012 Suzuki Kizashi - is one car to consider, they're clearing stock for these cars are an amazing discount. When it comes to looks/design/value this car has it all like 175hp/230nm engine with paddle shifters, keyless entry system, push button start engine, 4 speaker 2 tweeter 2 subwoofer in car entertainment system built-in, DRL, Projector headlights, 6 airbags, 5star NCAP, memory leather seats, etc. That's alot of tech for the price.....the compromise? They aren't sold in great numbers so in the future spare parts availability and price would be an issue....but a rare car which looks as good as this wouldn't age as quick so it will still look good for a long time to come.

Civic/Altis/Sylphy - all the 1800cc variants are within your reach and if you add another 10k to the budget you can aim for the 2000cc variants.

Lancer is also within your reach but then you might as me why bother buying a Lancer since can get a Inspira which is cheaper? Well, look here a Lancer would get these things which are factory fitted (you can buy a cheaper inspira and modify it but then you don't get factory warranty)......sunroof, keyless entry, push start button, leather seats, kenwood 2din entertainment system with GPS, and lastly Japan CBU with 5 years warranty  or consider the much more powerful Sportsback like this one which is on clear stock price
