Since flooding happens so often here in Manila, it is best to get an SUV. There are a lot of SUV's that fit your budget, but not all of them are really capable of water crossing. 4x2 lang, puwede na.
I would suggest Ford Everest. It can comfortably sit eight, it's a diesel and the high ground clearance is really a plus.
I'm not so sure how much money will be left from you but say it's around 500k.
For 500k, you can get a second hand 10th gen Altis, or an 8th generation Civic, both are tested for its reliability.
