I like this sorta thread. Nevermind he comes in asking about owning a nice car and all, but at least sets realistic expectations and provides complete info.
So let's break this down a bit. There's a EVO VIII in ZTH that's selling for 90k that's almost stock. So I'll use that as a guide.
1. Your salary is 4k + 1k a month. Banks will only look at the 4k, and take 30% of your gross salary as your loan capability per month. So that's about RM1200 approvable loan. Do you have any outstanding credit cards? Property under your own name or shared? Ptptn? Deduct all that from your salary before taking out 30% as your approvable monthly instalment.
2. You have a Lancer. I'll assume it's the 4B11 generation one. Resale value for a 2012 model is about 50k. So the Evo being 90k means your loan will be 40k and interest on used cars isn't cheap, I'm gonna guestimate it about 5%. Max loan for older cars these days is 5 years. So that means monthly including interest for 5 years is roughly about 850 a month.
3. Petrol on a Evo is about 6 to 10km/L max. Full tank of RON97 40L is RM78. KD to Subang and back sounds like roughly you travel 70km a day just to work. So 20 days work (weekends off) is 1400km and if I take the average of 8km/L fuel consumption, that's roughly 5 times refill in that 20 days. So your petrol bill in a month will minimally be RM400. This is not including weekends, if you include - it'll probably shoot up to RM600 depending on where you go and whether you boost or not.
So that's RM500 (average) petrol and RM850 monthly instalment.
4. Then there's maintenance. The VIII is not a new car - parts will break down, things will need replacing, the oils alone for this car will be expensive since you'll be using the good stuff for the engine, gearbox, LSD, er.. I forgot one other thing. I recall it needed 4 types of oils to replace. Then there's the tyres. 17" reasonably good tyres go for RM400 a piece for roughly a year. And since the car is turbo, your oil changes will be helluva more frequent than NA. Maybe every 5000km change oil?
5. Evo's are very high on the thief list. You'll be worried about the car day in and day out if it's a daily. Then the amount of money you'll end up spending on security will add up to be about 3k+ (I did something similar to my car in the day).
Not trying to discourage you but just laying down the facts. Evos are awesome cars. Just that most awesome cars need a lot of money to keep it awesome.
