It appears to be a Le sabre? Can't quite make out the quarter panel emblem. But this is between Benton Harbor and Kalamazoo on the west side of Michigan. Not mine! Mike
That really is a slick automobile, would like to have seen a little more information but still it is cool.
Wonder what it looks like underneath. being a Michigan car I'd be willing to bet theres plenty of rust.
No nailhead installed in the LeSabre, it's a 340 with an ST400 transmission. The regular LeSabre had a ST300 transmission.
