The Guardian has a consumer piece on a hire company generally being awkward when one of their cars was caught in a flood. The final statement about driving it after the flood struck me as kind of the opposite of what I would have thought. Here is some context and the quote:
I collected a hire car from the Enterprise desk at Tarbes Lourdes airport last July, and drove it about 12 miles to my holiday accommodation in Bagnères-de-Bigorre. That evening there was a severe storm that caused flash floods across town. Water entered the hire car, which was parked on a street at the top end of town, and left a muddy residue. No damage was evident, and the vehicle was working perfectly when I drove back to the airport four days later. I showed the residue to the Enterprise staff, who thoroughly inspected the vehicle and drove it a short distance before assuring me that everything was OK.
[Enterprise tried to charge him for the writeoff excess but backed down saying] “We are confident that the extensive damage to the electrics was as a result of water getting into the vehicle. We also maintain our concern that it may have been unwise for the customer to drive the vehicle, knowing water had entered it. However, on this occasion, we will cancel the excess charge as a gesture of goodwill.”
In this circumstance, if I was driving my own car, I would have wanted to start the car and get it drying as soon as the water appeared to have drained away, specifically to prevent the electrics from corroding. The implication I get from the above is that it could be worse for the car to be driven than be left, or perhaps even be unsafe.
What sort of damage could driving do in this situation? What is the "wise" thing to do after your car has been in a flood?
