It's a very rare 48 Merc Limo not a 49.
Should be good for 10 to 20 grand once the hawl it on shore. looks pretty complete.
The COast Guard sunk it sadly.
There were few cars built during the war. It was about three years before the passenger car assembly lines got running again. This vehicle would have been one of the early postwar products. I remember the first new car I saw, a 48 Ford coupe with a number of ecstatic soldiers joyriding around post.
