A garage local to me towed in a Range Rover Sport TDV6 a year or so ago.
It had been in a flood and stalled.
The engine still ran but no one had told the insurers. The garage proprietor fancied the car so offered the insurers to buy it.
I'm not sure what happened, but they turned him down and wrote it off, he then proceeded to pour water into the air intake to kill it, apparently it took about 2 or 3 minutes before it died!
however, that one was riddled with electrical gremlins, but then it probably was before it left the factory.
