Got me thinking about what car we could use? I'd say a 60 cause with that
big ol concave nose you could stuff some fancy gadgets on the nose and not
stick out past the bumper!!

Now you got me going wondering what would have happened to the Corvair if Dr
Emmett Brown got hold of it. The 1960's seems to be a period Back To The
Future seems to have ignored. Maybe somebody will write a prequel?

But, thanks for trying!
