Ang Innova 176mm (IIRC) lang ang ground clearance pero pareho ang wading depth sa Forester which has around 40mm more ground clearance.

Easiest way to measure a car's chances of outright survival in flood is to look for the position of its air intake, since game over agad kung napasukan yan ng tubig. Diesels are also less susceptible to water as compared to gas engines due to their lack of spark plugs. So I'd go for the Sportage or Tucson CRDi which aside from being diesels, if I remember correctly, have their air intake at hood level.

I once saw a CX5 cross a flood in a low portion of East Avenue near Philippine Heart Center during a typhoon last year (forgot the name). Ang haba ng pila at mga bus lang ang may lakas na loob dumaan. Nagulat ako nung nakadaan siya, submerged ang buong bumper at umaapaw sa headlights. Kinaya naman.
