Hummm, For some reason I recall my first car looking much like that. It was a 1961 Ford S/W with a 6 and a slush box. And I was in water & mud.
But after looking it over and having another can of courage,(I think it may have been Bud) I just fired it up and backed it out. Still dont know why it came out. But it did take me nearly a day to clean out the mud from the inside of the car. Thats not counting the time it took to clean the out side
