I have the opportunity to buy a xf that has been in floods, just how deep I'm not sure! but I should get it fairly cheap. Should I be worried? apart from rusting of wires etc what else should I excpect mechanicaly wise? could I simply drain all fluids e.g. oil, tranny oil, brake fluid and replace it with new fluid and it will be fine? the car is across the country so I'm abit nervous dont know if it starts either any input would be great.
