Bad idea... bad, BAD idea!
If the car was flooded as bad to make you worry about this, drop it like a toxic hot potato, and don't buy it. You could have damaged electronics, you could have mold, you could have rust issues, you could mechanical problems from water in the transmission, differential, axles, engine, and anywhere in between.
If you don't believe me, ask ANY mechanic (except the one that might be trying to sell you this) and you'll get the same answer. It'll probably turn into a money pit. Or read the article below from Click and Clack - the guys on cartalk, on NPR.
