There aren't many cars up to floods.. we have the muddy road here and if that's the case (and we are stuck) the car stays behind or we are. Once we been home for 6 weeks which isn't an option for you.
Like you say all the new cars are problematic (we had them - one part doesn't function and it can be caused by 18 different parts and of course the workshop will replace one part after the next till the problem is solved and it's always very expensive. It's made to replace or to throw away, not for being fixed.

Two feet is a lot and you cannot get a car that higher with different tires.

I hope your father can fix it and some solution will be on your way.
I keep my finger crossed, a warm embrace to you, dear friend.
