At last I decided to keep my old junk for good. Since the price of petrol has gone up, no point spending more buying a new car; just maintain the current car will do. If the engine gave way, I can always get a used engine from midwest auto recycling. It is better than to suffer month after month paying for car loan.
My old junk has been repainted. It no longer looks like an old junk. Next, the tyre needs to be changed. It easily punctures when the "flowers" are almost gone. Now, I need to decide whether to get a used tyres or a brand new set of tyres. Moolah talk again! :(
