Depends on individuals really. Weigh out both conditions. New car still has chance of it having to repair from time to time. Juz like Samsung phones, it is designed to not last long so that money keeps flowing into their bank account. Though it's less chance and tech wise, you save on fuel and also safety.

Kelisa is like a rare car nowadays. Its still fuel effecient. I overhauled mine not long ago and my mileage is from 390-400km/full tank before overhaul to 470-490km/full tank. Its a hefty price to repair but I guess it goes a longer way. Just need to change crappy parts from Perodua to Japanese and it may serve you well enough. Plus, in a city like KL, Kelisa cilok mana oso can get parking. Ppl bang oso not as painful as a new car. Just my 0.00002 cents

Saw a post here before.. someone took 4k to repair, but the car can last another 4 or 5 more years. compare with ur pocket with new car instalment (new) or worrying of the old car, its your call of which you prefer..

As I wrote before, I dun have the budget for new car for the time being. Luckily mine still serving me well. (Also 2006) In the future if I have the budget and choice, I might consider trade in.
