more drills here

Civic Hatchback might not be sold in Malaysia officially.
Since Honda Malaysia took over we've only got sedan versions of the Civic.
I don't think we'll get an official Civic Hatch, maybe grey imports like Naza will bring it in, but remember grey imports don't have the same warranty and spare parts availability like cars bring in my Honda Malaysia.

Civic = C-segment
Jazz = B-segment

so Civic bigger.
since you're buying cash here are some poisons, lol 

1980 Ford Capri - the owner seems to have taken care of the car really well and looks like a good buy and drive car, definitely a collectors car. Only issue might be getting spare parts for this car.

1992 Honda Prelude - looks like another well taken care of car which has some kits for that JDM kind of look, i'd prefer it to have the original steering as a sports steering usually (for me) doesn't give the best "feel". Probably the only thing to complete the race car look is getting some new bucket seats or maybe some refurbished bucket seats from a Type R model. Maintenance isn't really expensive for this car as parts are mostly cheap but engine oil requirements are quite big being a 2200cc engine.

Thinking to try a conti?
Here are a few options under rm20k
2000 Alfa Romeo 156 Salespeed - the only one in this budget with an automated manual gearbox, is reliable but gear changes aren't smooth like normal automatics but performs gear changes fast -- F1 technology. One might choose this car purely on it's Italian good looks, good gearbox and fantastic interior.

2005 Skoda Superb 1.8 Turbo - the only turbo in this budget range and also the youngest being a 2005 car, this is because Skoda's have a terrible resale value so good cars also devalue to nothingness. Size wise it is big and comfy like a BMW 5-series it uses the same 1800cc turbo and 6AT as the older VW Passat, it shares most parts with the Passat so you don't really need to worry about getting spare parts for this car eventhough Bermaz aren't selling anymore new cars but they maintain parts and service for this car plus you also can buy parts from VW Malaysia but these two options although can solve parts issue ain't going to be cheap. You might want to choose this if you like turbo's coz it is addictive 

2004 MG ZT 2.5 V6 - this is a made in UK rare dinosaur, the company went bust but it was sold to some chinese company in China, they have continued to support this car although it might not be easy to source for in malaysia because of a smaller user base -- i know many owners club do bulk purchase via distributors in china then taobao it over to malausia. Tax wise it is a hit/miss so be aware of that. If you want a piece of British motoring history, character and rarity this is the one to choose.

2000 BMW E39 2.5 - probably the only instantly recognizable model and it's looks has aged pretty well. If you're looking for a solid conti which is instantly recognizable and have high prestige then this is one you should go for. All 4 cars would demand the extra effort and TLC to maintain them to be at peak performance, the extra effort is needed to source for good yet cheap spare parts as these cars can burn a whole in your pocket and cost more than the purchase price very very quickly.

2004 Audi A4 1.8 Turbo - more or less the same as the Skoda above but it is a smaller 3-series size.
Proton Iriz is a good car if you're looking for something with good specs and safety features. Proton's new range of cars (not based on Mitsubishi technology) have yet to fully prove themselves in the long run especially if Proton can keep spare parts price as low as during the Wira era. At the moment there aren't much Iriz on the road thus economics of scale isn't helping to push down the prices of parts. Although potentially much more expensive to maintain it would be much safer to be inside if an accident ever occurs. Plus when I say expensive it is relative to it's price range as Axis/Myvi all are near it's selling price but are cheaper to maintain while it is still cheaper than Japanese makes or equal to them -- it is not going to be expensive as maintaining a Conti B-segment.

Perodua Axia is a good car but it is more basic. Lacking the specs and safety featured touted by Iriz which shouldn't be a crying point because Axia is supposed to be A-segment car while Iriz B-segment, of course a higher segment car has better features. Axia should be considered if you just need very basic transport within the city and don't travel on highways much -- KL to Klang is fine, not KL to Melaka -- as such cars aren't built for sustained high speed cruising and highway speed accident.

2011 Nissan Latio - for used car you can consider this car, a sad thing about nissan cars is that they don't hold their value as well as toyota/honda cars in malaysia but that's a problem for first hand owners, if you're looking for a second hand car you should always see what nissan has. This car is pretty good, size wise it is C-segment, decent 1600cc engine and 4AT gearbox. Reliability, ease of getting spare parts and the price of the parts are positives for this car. Although the engine is big enough for comfortable highway cruising it is good enough for short trips to nearby states, but a longer trip to places like Penang and Kuantan might be tiring listening to that punny engine roar and droning sound. Probably the only major fault is that it is pretty ugly but usually hatchbacks with bodykits look pretty good.
Option 1 is going to cost a bomb in terms of roadtax, insurance, fuel cost and maintenance. Service for a BMW 3-series runs anywhere from RM500 to RM2500, S-Class is a few levels above 3-series in terms of not only prestige but also maintenance cost.

Option 2 is a decent choice as it is more common than the S-Class but it is still a richman's car so upkeep and maintenance is still on the high side. I found a 2011 Merc E200 for sale under your budget and it is unreg, in my book that's better than buying new because usually unreg cars are from grey imports and when they sell something at this price range the car looks and feel mint new, can't really say the same for used cars even high-end models like E-Class even at this price range, unless it was a company car being sold off.

Option 3 you can go for 2011 Merc SLK200 for around 100k then spend the rest of the budget for an older E-Class if you're insisting on getting an E-Class else this is what I would recommend.

Option 3A
2011 Merc SLK200 @85k
2012 Merc C180 @85k

both are mercs but instead of an E-Class it is a C-Class, reason is the SLK is the rarer and more expensive to buy parts of for the two so at least if anything happens to the SLK you still have the C180 to drive around as it is a reliable car which is much more pocket friendly for this range of cars.

Option 3B
UNREG 2008 Scirocco 2.0 @ 95k - no 1.4TSI engine or 7speed DSG problems, this is the reliable 2.0 engine and 6speed DSG that's also inside the Golf GTI. Seeing that this car is quite popular on the roads it would be much cheaper to maintain and get parts for, of course you look a little bit on the prestige side but you get a more reliable sports car plus being unreg you can register a new number plate and get bank loan interest rates as a new car.

2007 Porsche Cayenne Magnum @ 87k - the upkeep and maintenance for this car would be near or exceeding the S-Class, however in terms of prestige and performance it is quite an overkill. One of the biggest reason you see many Cayenne up for sale and on the cheap (lacking high resale value) is because Porsche service centers with qualified Porsche mechanics are limited, certain parts may have to be flown in from Germany (which are usually expensive), and that yearly thing is a killer (insurance around rm3000 and roadtax around rm4000) is a great filter for the kind of people that can afford such cars -- someone that can afford to pay rm7000 when roadtax/insurance needs to be renewed.
which car only 2 door?
yeah, that's the risk of having a cool car.
for under 8k cash and looking for good proton's.
my best guess are the Proton Wira SE and Satria SE.
they're both considered the last model update before retirement thus should be the best.

2004 Proton Wira 1.5SE Manual - i've had wira's before and i can tell you the only good automatic in the range was on either the 1600cc/1800cc models which is a 4AT, that gearbox and engine combination was good for a fast and responsive car, but they stopped production before 2000 so such cars are older. They continued production from 1300cc/1500cc engine models but these were paired with a 3AT which although robust and reliable didn't have enough gear ratio's for a smoother drive and better fuel economy. Thus driving one of those like a slug would only give you good fuel economy else you're looking at 300++ kms per tank of fuel usually which is alot considering newer small cc cars like Mazda2 can do double that (of course also at double the price). This is where this advert comes in as I was searching online for one of the latest models of wira before they discontinued it and the Wira Special Edition is probably the best of them with a nice and sporty interior black and red interior with sport styled seats and the updated steering wheel. Although from the looks of it the outside could need a new coat of paint which could run anywhere between RM800 to RM2500 the rest looks okay as the interior looks nice and clearn (not too weathered) but the 1500cc engine and manual gearbox on these cars are usually very robust unless really abused by the owner so don't worry about that. I notice this car might have been through an accident the rear passenger door behind the driver is of a different color -- u have to check out the car for yourself and see if it is okay or not, pour water over it to see any leaking.
