@nprofile1q... Singapore and Malaysia also have an abundance of repair garages with well stocked parts counters, you don't even need to make appointments for basic repairs (my relatives are from Malaysia, and some of them have worked as mechanics).
Its not uncommon for folk to drive to Malaysia for the repairs as it can be cheaper (like Dutch people driving to Germany for cheap cigarettes / booze / petrol)
As the COE can cost as much as the car and has to be renewed after 5 or 10 years, a lot of motorists will just export the car and get a newer one, there's plenty of buyers from Commonwealth country where folk drive on the left...
