I owned Proton, Honda and Nissan.
All the SC are manned by equally incompetent staff.
Probably the same people that go round and round different companies.

You get better service if the cars are not selling well. I was quite disappointed with Nissan bcos they have few SC and they sold so many Almeras. So they were so busy, hardly got time to really check.

Honda sold many City and Civics. So they are pretty busy too.
