i would avoid unless you know exactly what happened to it, apart from siezed engines which will be fairly obvious there are the hidden issues regarding electrics suffering from corrosion. I know of a fairly late vehicle that suffered flood damage to about 1/2 way up the body, the complete vehicle wiring loom had to be replaced all the electronic modules many of which are hidden under the carpet, they control airbags etc.also side airbags had to be replaced, the list went on. Then it had to go to main dealer to be reprogramed and sort the other issues out with the electrics ...cost £1,000s,
at the end it was supposed to go on a forecourt, it actually ended up being sent to auction to get out of it...a ticking time bomb.
