Never did like Mantrade. Too crowded, so you don't get good service... but my problem was I lived very far away, so hindi ko sila kayang tutukan. It might be different now, though (we sold our Nissan five years ago.

Ang tip ng uncle ko who did get good service at Mantrade? Go in with the car on your first visit, and if the job looks like it'll take a while, offer smokes and/or drinks to the service crew working on the car. A little PR goes a long way.
