Thank you very much for all your responses. However, I would like to clarify some points - 1) We were out of HK for 6 months, when we were not in HK, we have someone to switch on the engine on a regular basis, just to make sure the engine runs ok and battery is working. Plus, we are just a weekend driver. Therefore, we only drove that little.
2) We know the car is already 18 years old, however, when he sold us the car, he didn't mentioned anything like OH, the car is freaking 18years old, therefore, you will get a lot of problems. The fact is he is a great seller. He just keep telling you - Oh, the car is beautiful, the body is gorgeous, the engine is perfect, what my lovely baby... blablabla..
Since his words were all polished, we do believe the car has no major problem like overheating. Of course, we know there will be some minor problems. We are aware of that. Just we can't believe after he fixed the car, we drove 2 times only. The car had the same problem again. We bought it to our garage, the mechanic believed it wasn't fixed probably.
3) The fine. Let presume he didn't know the fine in the first place. However, I emailed him and told him about this issue... How can he not realised after I told him??
Why not just admitted that instead of ignoring it? The address that we got the fine was the address of his garage. So, why wouldn't he know about it? HK$3xx is nothing. Its just about the Principle..
If you guys think I am being silly to complain about this fact, then we just have different principle in life. You made a mistake, just simply tell people what you did. Its not a big deal but when you hide and ignore the fact that you made a mistake, then it's a problem!
4) Warranty. Even the warranty is expired. However, the fact is he didn't fixed the car probably during the warranty time. So, it doesn't matter within/without the warranty. Because the car has hidden problem. I don't know any thing about car, so it means I deserve all these trust related issue.
So, it's exactly the same as Lehman Brothers issue. All these elderly deserve to this disaster because we should blame them have no knowledge about it. They trust the bank and believe what they told them, therefore, they deserve all these?
My post is just share my experience with you. Just to remind you not to follow my steps. If you don't agree with me, it's ok. No need to shift the blame on me! Thanks.
