I'll vouch for Toyota BGC as a good service station. They are very responsive in terms of inquiries and follow-ups. One of the fastest turn-arounds too.
Not very good but not too bad... Manila Bay. Their turn around is a little bit too long. Express maintenance is 90 mins not their promised 60 mins service.
Worst... Pasong Tamo comes to mind. Sobrang gulo ng service reception for maintenance and ang tagal magbigay ng quotation for repair to think repaint and clip replacement lang naman dapat ang gagawin.
