To renew it or to buy a new one

100,000k is just far beyond my scale... The price is already twice what it was five years ago.

As PQP is calculated based on average of past 3 months, COE's price should be taken in to consideration as well as car's conditions...

If my car is still in good condition, not much repair is needed, and the COE price is acceptable recently, renewing it would be a good choice. But judging by the recent trend and expectations of COE prices, at least it would not be a good idea to renew it from my perspective.
