Need a bit of help. My Z3 got flooded in the Nashville 2010 flood. I want to try to recover the car since we liked it so much. I need to start from scratch. Any suggestions and recommends are appreciated. I haven't started the car since it was flooded. Shorted out the battery. Water got up to the top of engine and up to the lower dash interior. Hope I can take apart, clean and repair. Is it a lost cause? Where should I start first? Thanks.
