I hope someone can answer this...

Im schedule for 20K PMS. I bought my MZ3 in Mazda Alabang. The 10K PMS was done by casa in Alabang.
For the 20K PMS due to cost differences between casa, im looking the possibility to have it done by other CASA, Makati or Greenhills perhaps.

Now, is there an issue availing the PMS from other casa? warranty issue perhaps? What are the requirements or documents needed? Do I need to inform my original casa?

Any suggestion for good casa with good service at reasonable cost for 20K PMS?

Appreciate your feedback.. Thanks!
