Looks cheap at £45k but BEWARE - i've had flood damaged cars before and they are a TOTAL nightmare - what happens is the electric connections will corrode after a while and everything starts going wrong. On a beast like this i'd hate to think what could happen...

Add to that the smell NEVER goes and it's not such a clever buy. Just my 2p!!
Cheers.
