I've had mostly good experiences with Minerva in Biņan, but I may be biased, kumpare ko yung manager doon.

I've only had a few emergency jobs done at Filinvest... broken water pump and cracked timing belt on my Mazda. Service was good, but then again, the mechanic was one I knew from the other branch, so he did well by me.

Whenever I have alignment done, mausyoso ako... I always ask about settings and instruct the mechanic if I have some "non-factory" settings in mind. So far, have had no bad experiences with such. Maybe it's just your bad luck that the owner or floor manager is like that... I've never heard of such a thing.
