One issue ComfortDelgro was very concerned with Merc , was the
cost on maintaining .... they cost more to maintain than Azera
.
In terms of spare parts and repair .
When they bought Merc into their fleet , their targetted Merc's
life span on the road is said to be 10 years , but with the
changing market , now 5 years scrap , cos depreciation wise , Merc
made less money ...
So they switch to Azera as one alternative options .
