Giving best trainers to train you, i would like to work with the HQ rather than DEALERS because dealers u can't expect the same management, some are bad some are wise. it's important to pick the best company before you give your service for them.
Service advisor for service is a though one, this because you are dealing with customer when they want to service the car, for 1 day you need to attend minimum 10-15 customer/day. Need to update all customer what happen to the car and what the progress. Need to be gentle to all customer and make them happy service with you.
